It's teletext data (VBI I think is the proper name), streaming of text
data within the video signal.  It was designed to be hidden in the bit
of the picture you couldn't see on an analog television.

AFAIK the only way to get rid of it is to tweak your overscan settings
so that the top few pixels aren't visible.

[mythtv-users] Line of garbage at top of screen

[David Abrahams]

When I watch recorded material on OS X there's what looks like a one
(source) pixel line of seemingly random black and white pixels.  The
source material is fine; I don't see the garbage when I play it in
VLC.  Does anyone know where this comes from or what can be done about
it?  (Trac is down or I'd have made a ticket)

Thanks,

[mythtv-users] Scheduled Recordings are keyed off of the callsign field

[David Whyte]

Howdy,

I went and adjust some of the channel names in mythweb so that they
showed up down the left of mythweb a little different (to save space
more than anything).  The text I changed was the 'callsign' field in
the mythweb > Settings > Channels page.

Anyways, I just noticed that all of my schedules had been cancelled
and immediately realised why, however I don't understand why it is so.
 I thought each channel would have had a unique ID which is what we
would key off so this 'callsign' field can be updated however.

I am sure there is a logical reason for why this has heppened, I am
just hoping someone can explain it to me.  Everything is OK, by going
and updating them back they have come back.  (Although I had to
restart the backend for the changes to take effect, which is why I
didn't pick up the problem sooner).

Cheers,
Whytey

[mythtv-users] Icon for mythfrontend

[David Whyte]

Hi All,

When I installed mythTv from ATrpms under FC2 a new start menu item (a
windows term I know) was created so I could start the frontend and I
placed this in the panel at the top of my screen so it showed up as an
icon with some funky text that said 'mythTV'.

Under ubuntu's packaging, there is no new menu item (which is fine, I
like it that way) but I have put my button back in the panel at the
top of the screen and would like the same icon (or a better one if
there is one).

Is it possible for someone to email me (probably directly is best)
their icon so I can use it?

Cheers,
Whytey

Your right.  I found an email from way back when I was setting up on
FC2 and I had to manually load all of the following.


I tried them all just now and afterwards dmesg shows that the frontend
was loaded.  Schwet!

However, I obvisouly don't think I should be manually loading all of
those.  I believe it could just be the frontend ones, but I don't
know.

/me shakes fist, kicks self, looks up and asks 'why do you make life

For the record, there is no trace of the permissions.d folder.  I have
rules.d, but it looks different to what you have for permissions.

No worries Phill, no doubt you will figure out how I go in the coming

I will look into that Phill thanks.  I managed to create 4 (???) dvb
'things' (i.e. /dev/dvb/adaptor0/*) but myth still had trouble.  You
may be on to something.

Just a quick question, which flavor of linux are you running atm?


The problem with trauling the web is that so many people have slightly
varying setups and do things so differently that there doesn't appear
to be a common way to get this working across the board :|

I know it will work, it worked under FC2, it is just getting there in
as little pain and with as few sleepless nights as possible ;)

Thanks,
Whytey

[mythtv-users] No /dev/dvb with AVErMedia DVB-T 771's with Ubuntu 5.10

[David Whyte]

Hi knowledgable folks...

I am trying to get my new install of Ubuntu 5.10 working with my three
AVerMedia DVB-T 771 cards.

I was a linux noob when I first got mythTV going, and I had a friend
set them up with my under FC2, but after encountering apt-get HELL a
couple of weeks ago a new install of linux was required.  I decided to
go the Ubuntu route because it is just so nice.  The problem is, I
have just realised that I am still a linux noob when it comes to
getting hardware working.

Anyways, from what I can see, the cards are recognised as the output
from dmesg is as follows:

However, there are no /dev/dvb devices created so mythtv-setup does
not know the cards are present.

When I set this up in FC2, I didn't have to do anything really special
(it turned out) and I thought it would be even easier under Ubuntu
5.10 with a much newer kernel.

Does anybody have any ideas about what I am doing wrong.  And please
don't say anything about rebuilding the kernel else I might wee my
pants :(

Cheers,
Whytey

Mythtv is probably expecting to change channel via a channel change
script, as it would do if it was controlling an external Set Top Box.

I think the standard procedure in your case.is to give it a dummy
script script, that always returns success.

Hmmm.  Yours seems labelled differently in your documentation than
mine.  I got documentation that looks like here: 
http://hauppauge.lightpath.net/manuals/qi-pvrpci-150250350.pdf

Looking at the diagram of the back of the card on that URL, I was
referring to the "A/V Output connector."  In any case, thinking about
it now, as long as you're using the Svideo/triple RCA adapter and
you're getting menus **ON THE TV**, I can't imagine you don't have it
in the right port.

It will if you do the loopback I mentioned in [4].  The non-TV apps
only talk to a sound card.  They don't know how to talk to the 350's
audio decoder.

Nope, video worked from day 1.  Had no audio at first, but that was a
problem with it actually being muted in the card.  testioctl fixed it
right up.  [If anyone hits this in the archives looking for the same
problem, search for "pvr 350 audio testioctl"].

If you can get TV audio and/or video in any other way (xawtv, dd
if=/dev/video0 of=/dev/video16, whatever), I'm stumped.

If you can't get video in any way (looking back over your posts I
don't see one), I'd check that you don't accidentally have the antenna
on the FM input instead of the TV one (see the documentation URL
above) and, if it's not that, try to find a windoze box to slap it in
to make sure you don't have a defective card.

HTH!

Hmm  that's interesting - so I'm wondering if I've actually got my VCR
connected via the RF lead to the tuner input at the moment?  I
definately have used the S-Video input in the past though, because I
had to connect the audio in separately.

I suggest looking to see what other /dev/video devices exist on your
system, and trying them in place of /dev/video0.  I think one of the
setup pages of mythtvsetup shows you which input is on which device.
I'm afraid I don't know enough of the theory to suggest a more
scientific approach.

You've probably already done this but ...

Have you looked at your system logfiles?

mythbackend.log, mythfrontend.log and /var/log/messages spring to mind.

Apart from giving a clue to what's going on, writing to the log itself
causes disk activity.  On my system, mythmusic was creating a racket
on the disk, which turned out to be lcdproc writing copious error
messages to /var/log/messages.

Just look for files on /var growing large very quickly.

Re: [mythtv-users] New to mythtv, need help

[David Schmidt]

DISCLAIMER:  My 350-based system is not fully working yet, but since
I'm in the middle of setup, I'm rather familiar with options for
it.   (If I'm wrong on any of this, someone please correct me.

1)  The 350 *can* output sound (use the red/white RCA plugs on the
svideo adapter cable that should have come with it--make sure it is
plugged into svideo out, not svideo in).

2)  If you do this, however, you can't control the volume in Myth. 
You'll need to use your TV volume control.

3)  Also in this case, only live and recorded TV will have sound
MythMusic and most, if not all MythVideos will be silent (and
MythGame, if you use that).

4) You can solve 2 & 3 by getting a sound card and looping the
red/white RCAs into sound card in, then sound card out to your RF
modulator or VCR.

5) Using the 350, your machine specs should be passable.  My
(prototype only) system is

- P3/450 MHz
- PVR 350 in/out
- SB Live/Value
- 384 Meg RAM
- 20 Gig IDE HD (boot/root/apps/db)
- 40 Gig IDE HD (video).

Like I said, it's not 100% there yet (the same overscanned menus you
see, a few usability issues), but except for very long menu
transitions (1-3 seconds) and startup times (10-12 seconds), it's
performance is fine.

HTH!

Does grep work with wildcards?  I'd have done:

find / -name "*20060112*" -print

The directory for recordings in specified during mythtvsetup (the
backend setup)  I think by default it's called /store, but that
probably depends what package you installed from.

If your file did get recorded, but isn't showing up, then that's
probably something to do with recording groups.

Manual recording with mythtv is a bit of a palaver.  You might find
the following command easier.  It's what I use for recording from my

Yes, it's fixed in SVN.  Unfortunately fast forward, skip forward,
rewind, skip back and E all have the same new problem: sometimes the

I just wanted to chime in:

After using MythTV for nearly two years, I moved to an apartment where I didn't 
have cable. I've moved again and now have cable, so this past weekend I got my 
MythTV box (and LAN fileserver) back up and running. I'm running Gentoo with a 
2.6.15-gentoo-r1 kernel. After much tinkering, I am down to just a few minor 
issues. One of them was the video jitter when menus and other OSD elements were 
displayed and Xvmc was enabled (I have a GeForce FX 5200 driving my Samsung 30" 
CRT HDTV with a 540p signal via a DVI-HDMI cable). Disabling Xvmc was not an 
option, as this is only a lowly Athlon XP 2500+ (overclocked to 2.0 GHz) with 
two PVR-250 cards and a FusionHD 5 Lite card on the way to replace a PVR-250.

I spent a couple hours wrestling with this issue last night, trying various 
nVidia driver settings (I had noticed it originally with the 6629 drivers, 
jumped straight to the latest 8178 drivers in Portage and still had the issue, 
so apparently it's not the >7676 issue with OpenGL Vsync others have 
mentioned). I played with nearly every option in nvidia-settings to no avail. I 
tried nearly every OSD-related setting I could find in the front end settings 
without success. Finally I stumbled upon this thread and this driver option. 
Adding the following line to my "Device" section in /usr/X11/xorg.conf 
completely solved the jitter w/OSD issue I was having:

Option "XvmcUsesTextures" "true"

So nice to be able to pause TV, schedule recordings, and skip commercials again 
(after a few months with just regular cable, I still find myself watching the 
commercials because I haven't yet got into the mindset that I can skip them :). 
Still need to fix LIRC, tweak the overscan settings, make sure MythWeb is 
working, replace the failing drive in my RAID array (1.04 TB RAID-5, also used 
as NAS; 8 Maxtor 160GB ATA/133 drives attached to a 3ware 7506-8 hardware RAID 
controller, but the SMART data for all the drives say they're OK, so I'm just 
waiting for it to actually fail completely), add the HDTV tuner card I've 
ordered, and replace the current sound card with one with optical S/PDIF output 
to connect to my AV receiver).

Thanks to all the developers for this awesome software! Lookin' forward to 0.19 
(is there a list somewhere of the new features?) And thanks to Dan for pointing 
me towards this fix.

Well it's pretty dangerous doing this without having a system to check

I'm pretty sure it's the 'M' key - the same key as brings up the menu

vlc worked for me - At least mostly it does:

Sometimes I get no sound - which I assume is related to the recording.
 All recodings are made using a Nova-T card and all have sound when
played back through mythtv.  Some recordings just have no sound when
played back with vlc, and changing the audio track doesn't help.

Sometimes vlc won't open any files at all.  This problem comes and
goes.  Clicking the link in mythweb opens vlc which briefly shows the
correct filename in the status bar, but it never plays the video nor
displays any sort of error.  When it's in this mood I'm unable to play
any files.  On another day it will work perfectly.  I have two windows
machines -  a desktop and a laptop and both exhibit the same
behaviour.

[mythtv-users] Mythtv 0.19 -> xbox and mac osx frontends (anyone done this with svn?)

[David Bennett]

Just wondering if (when the big switch to 0.19 comes) if anyone has
intructions on how to, or a running copy of the frontend for other
platforms? Ie. MAC OSX and XBOX.

The MAC OS X was easy to setup (just a quick .dmg download) but the
XBOX was somewhat a pain in the ass. I have (unfortunately) had to
reinstall my system and I am wonering if 0.19 will put my xbox
frontend out of comission for awhile?

I finally solved this mystery.  lirc-0.7.2 will work, however, you
need the lircd.conf.fusionHDTV from lirc-0.8.0 since the definition

Just playback.  My impression is that with XvMC you probably don't

[mythtv-users] TV sched is wrong; how to fix it?

[David A. De Graaf]

Somehow, my TV schedule database got some wrong info.  Possibly it
happened as a consequence of a recent power failure; I don't know.
The result is that the channels listed are off by one.  That is,
the programs for channel 9 are listed as showing on channel 10, etc.
Thus, it is impossible to record the correct program.
This bad data extends only through Sat. 1/21, so all I have to do is
wait out the problem.

Nonetheless, there are some programs on Sat night that I'd really like
to record, which are not broadcast later.  And I'd like to know how
such a problem can be dealt with in the future.

I'd like to delete just the schedule data and rerun mythfilldatatbase,
but I don't see how to do this selective deletion.
How do I delete and renew the schedule data from the mysql database?
Any advice is welcome.

If it matters, I am running mythtv svn from 0107, with a pcHDTV HD-3000
card on Fedora Core 4, x86_64.  TV signals are from a Mediacom cable,
using plain old analog NTSC modulation.  The TV schedules are downloaded
from DataDirect for Mediacom cable for our zipcode of 28739.

You can turn the directory structure into an iso disk image and import 
that into MythVideo just like any other video file.  Configure 
MythVideo to use xine as the player.  It can play the video from an iso 
dvd image with full DVD menu support.  MythVideo's Video Manager will 
let you specify the title and image to display in the browser.

Then, all I can say is to try again, preferably from scratch.  

FWIW, I had the exact same results as you Monday evening with lirc
0.7.2 and 0.8.0-pre4.  I got frustrated and deleted everything I had
tried.  Tuesday evening, I tried again, doing the same things, as far
as I could remember, and everything worked just like it was supposed
to.

You also need the "--driver=dvico" option when running lircd.

Not sure what this TV.COM script is about (although it sounds exciting!)

Unfortunately my mythtv setup lives in Japan so i think I will have to

[mythtv-users] Moving my mythTV install to a new distro (Was: Importing recordings after losing entire database and reinstalling)

I am in a very similar boat to yours.  I did an apt-get upgrade on the
weekend and somehow my server got hosed, with a bunch of kernel panics
and stuff on reboot!  The cause appears to be that glibc was upgraded
or something and there are bunch of binary dependencies that haven't
been met or that rely on an older version.  I managed to overcome the
kernel panic by disabling selinux at the grub screen, but so much of
my box is hosed I need to start again.

I am going from FC2 to Ubuntu (at this stage) but would like to be
able to keep the recordings on my /myth/recordings mount (which is on
a seperate HDD).  Can I simply export the mythconverg DB and re-import
it into my new Ubuntu mythTV when I get it up and running?  Should I
just export certain tables (I have messed up most of my theme
formatting too :P).  I imagine it is best to go from FC2 0.18.1 to
Ubuntu 0.18.1 rather than waiting for 0.19 to come out and import
metadata across different versions.

Can anybody give any advice?  I am quietly crapping my pants ;)

Thanks,
Whytey

[mythtv-users] Importing recordings after losing entire database and reinstalling

[David Bennett]

Well, during my computer upgrade I manage to fry my hard drive (not
the video drive, but the Linux Root)

I have lost everything on it and am left with my /video partition.
I have tried to find some answers on how to import this video back
into my new mythtv setup, but only come up with importing .avi's etc.

I am guessing that I have lost the show information etc. But is there
a script or a method for importing these .nuv files back into mythtv
so I can watch them from the "watch recordings"?

I don't suppose any of the program information is stored in the .nuv
files? (didn't think so!)

Well, kinda..

If you will *really* only be doing video/audio through the 350, it won't matter.

However, the 350 is only good for MPEG2 and framebuffer.  If you wish
to use MythMusic or (IIRC) MPEG4 stuff in MythVideo, those play audio
through the sound system.  In fact, to do those reasonably, you need
to loop the 350 audio out back into the soundcard in.

Also, without using the loopback/sound system, Myth cannot control the
volume of the (MPEG2) audio--you'd have to set your remote to control
the TV or amplifier level.

There was some good advice on Nova-Ts in the archives - fairly easy to

Do you have good DVB reception?
This is a good link for UK digital TV - what cable to use from the
aerial etc...
http://www.megalithia.com/elect/index.html

I currently have usually bad DVB reception (upgrading the aerial wire
next week) - and Mythbackend sometimes has problems 'cos it can't sync.
It's also impossible to say "don't record on this input" so as soon as
you get xmltv going it will schedule for it and you'll have to delete
shows by hand.

[mythtv-users] FYI : RAID5 adding a new disk

[David]

This announcement appeared on the raid mailing list today and I thought
it may be of interest.

If any of you are about to build a raid5 and have time/inclination then
maybe you could test this out before reverting to a more stable kernel
for 'production' use?

David


 Original Message 
Subject:[PATCH 000 of 5] md: Introduction
Date:   Tue, 17 Jan 2006 17:56:04 +1100
From:   NeilBrown <[EMAIL PROTECTED]>
To: linux-raid@vger.kernel.org, linux-kernel@vger.kernel.org
CC: Steinar H. Gunderson <[EMAIL PROTECTED]>



Greetings.

In line with the principle of "release early", following are 5 patches
against md in 2.6.latest which implement reshaping of a raid5 array.
By this I mean adding 1 or more drives to the array and then re-laying
out all of the data.

This is still EXPERIMENTAL and could easily eat your data.  Don't use it on
valuable data.  Only use it for review and testing.

This release does not make ANY attempt to record how far the reshape
has progressed on stable storage.  That means that if the process is
interrupted either by a crash or by "mdadm -S", then you completely
lose your data.  All of it.
So don't use it on valuable data.

There are 5 patches to (hopefully) ease review.  Comments are most
welcome, as are test results (providing they aren't done on valuable data:-).

You will need to enable the experimental MD_RAID5_RESHAPE config option
for this to work.  Please read the help message that come with it.  
It gives an example mdadm command to effect a reshape (you do not need
a new mdadm, and vaguely recent version should work).

This code is based in part on earlier work by
  "Steinar H. Gunderson" <[EMAIL PROTECTED]>
Though little of his code remains, having access to it, and having
discussed the issues with him greatly eased the processed of creating
these patches.  Thanks Steinar.

I've just upgraded my frontends to use the marillat versions. (I

For others reading this thread: they are complete packages and work
well. Given that most debian users will have marillat for mplayer and
xine; and given that "it just works" then IMHO it's a damn sight easier
to apt-get myth too if you just want the 0.18.1 version.

Oh, notably goom now works in mythmusic and mythbrowser works out of the
box.

William, going back to my first message, I have a version of tcrequant

[EMAIL PROTECTED] mjpegtools-1.8.0]$ tcrequant -v
tcrequant (transcode v0.6.12) (C) 2003 Antoine Missout

I downloaded the latest version of mjpegtools (1.8.0) and built and
installed, but I still have my old version.  The I did some Googling
and found references to tcrequant in the transocde packages, so I got
the latest version of that (1.0.2) and still I seem to have 0.6.12 of
tcrequant.  Just out of curiosity, what version do you have?  If
newer, where did you get it from, if you can remember.

I have an older 46" Mitsubishi TV connected via an RGBHV breakout 
cable.  I've wrestled quite a bit with different modelines and finally 
settled on a 960x540p mode.  I remember having the problem you describe 
with the display wrapped, but it was wrapped for everything, not just 
the nvidia logo.  I can't remember what modeline/configuration I had 
that problem with.  Here's the modeline I'm using:

ModeLine "960x540p" 37.26 960 976 1008 1104 540 542 548 563 +hsync 
+vsync

The TV is a Mitsubishi WT-46809, and it interprets that modeline as 
1080i.  It has been working very well for almost a year now.

My system configuration is quite a bit different from yours:

Fedora Core 4
X.Org 6.8.2
Nvidia driver version 1.0-7676
Myth built from svn version 6905

Thanks.  It looks like it could come in useful.

Out of curiosity (and likely going way OT even more), why do people
use avidemux?  Or mpeg2cut and other such tools?  I find nuvexport
does a great job of creating DVD compatible files and honors the
cutlist perfectly.  I would have thought it would have been the best
tool to base most of these scripts on, since it comes with any mythTV
package.

Is there something I should know about nuvexport?

[mythtv-users] Slightly OT: Burning an MPEG2 file that is too large

[David Whyte]

Hi All,

I am trying to burn a MPEG2 recording exported by nuvexport, but it is
too large to go on a single layer disc!

I remember just the other day reading about a linux command line tool
that can reduce the bitrate of a mpeg2 file.  All you had to do
basically was tell it what factor to reduce it by, such as '2' would
halve the effective file size, '1' would be pointless and '1.2' would
make it 20% smaller.

I know I could just change the quantisation (sp???) factor in
nuvexport, but I am keen to find this command line tool I stumbled
across the other day.  (Yes, I checked my history and google search
history too, but no luck).

Any help is appreciated.

[mythtv-users] A little OT: Problems with NetworkManager on Reboot

[David R Robison]

I know this is a little off topic, but...

My myth box uses a USB wireless adapter to connect to the network. I had 
a lot of trouble with the network dropping out so I activated 
NetworkManager (I'm running FC4 and KDE). Not the network stays 
connected almost 100% of the time. The only problem is that now the 
network will not activate when the box is started up. I have to log into 
the box and manually activate the network. Any help would be 
appreciated. David

Re: [mythtv-users] Think table as Class and record as Object

[David Rudder]

I think this is a good idea, but it's not as easy as all that. This is a 
fairly standard programming problem. The problem with simply modeling 
each table as a class is that it doesn't take into account foreign 
relationships. For instance, with the CardInput class, you'd want to be 
able to store a reference to the CaptureCard class, not just an integer 
CardID. So, you can say "CaptureCard card = cardInput.getCaptureCard()" 
and it will return a CaptureCard. Rather than having to say "CaptureCard 
card = database.loadCaptureCard(cardInput.getCaptureCard())".

I guess what I'm saying is that I think you have a good beginning here 
to make some very useful automation code, but you have to be careful 
that your classes match the data model, or it'll end up being difficult 
to use.

There's a Java project called Druid (available in Sourceforge. Search 
google for it). It'll automatically generate C, C++ or Java code for 
representing the data. It should help you get started.

Feel free to email me off line at
drig at noses dot org

P.S. I also have 45 tables.
P.P.S. Once you have the database modeled in code, what are you going to

Re: [mythtv-users] Software RAID problems - the unspokenmythtvproblem?

[David Bennett]

Yeechang and everyone else who has been so helpful,


 I must admit I am quite fascinated by the Raid and NAS discussions,
but given that I ran into the same problem of being unable to record
two programs at once on my software RAID, I am grateful for Yeechang
to try and help steer things back towards my original question.

Quick summary: When on a software RAID two programs cannot be recorded
when they start at the same time. The second program (always starting
0.3 seconds after the first) does not record and ends up as a 0 byte
file. This only happens when the video/recordings is on my software
raid. (this is key. i can switch over to another non raided hard drive
and have no problems doing the exact same thing!)

I an running linux kernel 2.6, 512mb, celeron (fairly fast but a
celeron nonetheless). I am using 2 drives in Raid 1 (had same trouble
with Raid 5 though) and am using a Sata IDE extender to add sata ports
(but this is probably irrelevant as I had the problem before I
installed this.) Some people have suggested that the celeron might be
the problem, but is this possible?

No errors on dmesg, and no errors on mythbackend.log until I try and
see the recorded programs on mythweb. Memory is full (as always... is
this normal?) but the Swap is empty (only 1%). Top doesnt show
Mythbackend anywhere near the top.

Here is what my log shows:

2006-01-12 20:59:02.889 Started recording "けものみち" on channel: 4 on cardid:

2006-01-12 22:09:00.037 Finished recording けものみち on channel: 4

the 2nd program's video file is 0 byte file size. (and the 2nd program
always does not seem to work.)

Suggestions so far:

celeron cant handle it (cache issues) --- a possibility?
memory -- not sure myself
drive spinning - maybe the drives are spinning down. this is also
possible but as they are sata i cant seem to change them with hdparm.

So much frustration!!
arg, any ideas? raid caching or the likes? (<-- i made that up!)

thank you kindly
david

Well I tried the various de-interlace settings available in the
mythfronted set-up screens.  For me the 'kernel' method looks best,
but it's pretty subjective, and your mileage might vary.  You can also
try with XvMC turned on and off.  If I remember right using XvMC gave
an improvement, but made the On Screen Displays unusable due to
extreme flickering of the picture whenever the menus were brought up,
so I leave it turned off.

Overall I haven't regretted changing from the 350's TV out. It enabled
me to play DVD's and use Picture-In-Picture and GOOM and other stuff
that the PVR350 couldn't handle in those days (though I believe it can
now with the new ivtv drivers).

The TV picture quality difference is pretty marginal. At first glance
I'd say that the nVidia output looks better - ie a bit sharper and
brighter, but the motion issue is definately there and some programmes
just don't seem quite right.

The other minor issue I have with the nVidia card is that I think I'm
having to overscan the picture more than the 350 did, to get rid of
the wobbly edges, and from time to time the overscan settings get
reset to 0.  I've had to assign a button on my remote to restore them.

Well if you're using KDE then Jarod Wilson has a suggestion in his
excellent howto

http://wilsonet.com/mythtv/

something to do with the 'focus follows mouse' KDE setting.

Now I'm using the ratpoison window manager with mythtv and Xine, and

Could this be due to your output method, rather than the capture? 
I've noticed it too since I stopped using my PVR350 for output and
started using an nVidia card.  Changing the de-interlace algorithm
improved things to the point where I hardly notice it now, but it's
still there.

Well my small[ish] children show no inclination to turn off anything
[lights, taps, televisions ...]  so I havent' had to worry about the
power-button on my myth box, which does a contolled shutdown of the
machine.

I'd like to know how you turn your myth box on using the IR remote
though.  I'm using the IR receiver that came with my Hauppauge Nova-t
and IFAIK I can't use this for powering up [I'd be happy to be proved

Well, that's a bummer.  It sounds like we have a mixture of people

[mythtv-users] Unpredictable Skip/Fast Forward/Rewind behavior

[David Abrahams]

When I use the fast forward, rewind, skip forward, or skip backward
keys while watching a recording, it's as likely as not that I'll end
up back at the beginning, which makes navigation quite difficult.  Is
this just a plain bug or is there some "technique" I need to learn in
order to make it work better?  I'm running the MacOS frontend built
from SVN, for what it's worth.

To answer your question (though the other suggestions are useful to
avoid accidental exits):

6:23:respawn:/sbin/mingetty --autologin mythtv tty6

In myth's .login:
[ `tty` = '/dev/tty6' ] && exec /usr/bin/X11/startx
/usr/bin/mythfrontend -v 255 2>&1 > ~/myth.log
which doesn't start it up if you login to the account on another vt

I find that if myth ever crashes or hangs (v. rare) then
ctrl-alt-backspace kills X and the respawn restarts it.

I don't run any window managers - don't seem to need them. YMMV.

I've never researched them and would rather build my own - but that's
not necessarily a 'rational' thing - more for fun and learning.
I don't think there are any technical reasons that it won't work. If you
have a single-box approach then spend more money on a decent mb (maybe
go Intel rather than nvidia/VIA), psu (really), case (eg lian-li or
other aluminium ones)

Yes. I have 3 Intel e1000 cards that are back in their boxes after I
(together with months emailing the incredibly helpful Intel driver
developer - who even got Intel to buy the same mb as me) couldn't get
them to work on my VIA based mb. I now use Marvell based ones - slower
but they work.
If you have an intel system then get the e1000 they are supposed to be
the best.

I could see in the new mythweb the ability to select the jobs to run

I didn't see that in the 'Recorded Programs' page.  Is it in there???

Just the other day I wanted to look at what had changed in MythWeb so

Re: [mythtv-users] Centralized NFS (NAS?) video partition

Hi Dave,

 Thank you kindly for your quick response. I think I am getting a
better sense of what I need to do and what I need to learn.

If you don't mind, may I ask a few more questions?


> If you want to buy an off-the-shelf NAS then that's different.

Do you think that is a viable option? I can't help but thinking if I
have this backend (a fairly large case too!), that I should use it to
run as my backend, and run a few drives in it on a RAID setup. On the
other hand I have been hearing many good things about ReadyNAS ... so
I am a little conflicted.

> high CPU and temperatures - and maybe DMA issues. If you are worried

If I do decide to go with a gig card, do you have any experience with
them? Should any brand/model be safe, or does gig networking still
have issues to be worked out with Linux?

Finally, would you by chance remember the option to keep the drives
from spinning down with Hdparam? Still no luck in finding the option
(or even if I can get it to work with my sata's) but I have a feeling
that might be the culprit!

thanks again for everything,

You say 'NAS'
my NAS is an old tower PC in the corner with room for lots of drives
(and lots of air).
If you want to buy an off-the-shelf NAS then that's different.

You can. Or you can have a seperate box with all the drives and nfs
mount it to your backend (and all the frontends, and your windows boxes...)
You can easily run NFS *and* samba (for windows access)
Having 3 tuners and a load of disks in one box has the potential for
high CPU and temperatures - and maybe DMA issues. If you are worried
about network bw, then drop a cheap gig card in both the NAS and BE.

wireless for FE is fine - if it glitches then no damage done. For a BE
I'd say you're asking for trouble. A glitch here easily causes data
corruption.

Well, the wiki has a fair bit (and you're welcome to add your experiences)

My system (which I think is pretty elegant/flexible):
* 1.2Tb (XFS,lvm2,raid5) server (6x250Gb SATA + hot spare 250Gb PATA) in
tower case. Athlon 1200, 512Mb RAM.
* BE: £99 dell server (some intel chip - dunno) 80Gb disk. 2 Tuners
* FE1: diskless (boots from NAS)
* FE2: 160Gb SATA (for now)

I also use the server for video editing.

Don't do this.

You shouldn't mix raidtab and mdadm
raidtab is obsolete with newer md. Uninstall it.

using mdadm the above would be:
mdadm --create /dev/md0 --chunk=32 --level=raid0 --raid-devices=2
/dev/hda1 /dev/hdc1

I suggest reading man mdadm (and why are you setting chunk to 32?)

If you decide to go raid5 then you *must* use mdadm -F (otherwise you
may well miss a disk failure - it's easy to do). Of course if you use
raid0 this isn't important since you'll spot a drive failure as soon as
the system crashes ;)

No problem.  That's how I use mine - no monitor, keyboard or mouse. 
Myth (particularly the PVR parts of it) are easy to use with only a
remote.

For maintenance I'd say you'd want the ability to remotely log in to
it from another machine over the network though, using ssh or vnc for
example.  Otherwise you'll be lugging a monitor and keyboard around
every few weeks.  In any case, the mythweb interface to the PVR is
particularly cool.

Re: [mythtv-users] Centralized NFS (NAS?) video partition

Actually after sending out my question to the list, I stumbled upon
the Infant ReadyNAS 600 page.

Does anyone use this?
Will it be able to handle 3 tuners + playback?

(it seems that any network device might be in trouble when it comes to
that much bandwidth. that is why I am thinking whether i should setup
some sort of nas/nsf on my backend and keep the /video partition
there...) (and use nfs to mount other directories for the other system
to get at!)

any ideas?

[mythtv-users] Centralized NFS (NAS?) video partition

[David Bennett]

Please allow me to apologize for the mangling I am about to do to the
following terminology. I am still feeling my way around Linux and know
what I want to do, just am not sure how to go about doing it (or if it
is possible.)

I have been getting some help with some software RAID problems I have
been having, and after reading many of the responses I have been
inspired to rework my system.

Here is what I would like to do:

I would like to develop a storage system that can:

1) have enough bandwidth/speed (whatever) to be used as the /video
partition on a mythtv system with 3 tuners.
2) have security (in the raid  / storage sense)
3) Be accessible by my home network (windows / mac / linux)

Obviously #1 is most important. This needs to be able to be my /video
partition for a fairly intensive 3 tuner system (ie three concurrent
recordings and maybe viewing on a frontend.) (4 streams)

Is this possible to do with NAS (I am guessing that NAS is referring
to the device, and NFS is how they link together?)

I would like to have my mythtv/music/videos on a storage system that
is accessible to my network and can be put in a RAID array. I am not
sure what to do. Should I be looking at throwing a whole bunch of my
drives in my backend and nfs'ing (samba? or is that different) to my
windows/mac?

Is there a more elegant solution to have just the storage somewhere
and hook it up via a network? (can 10/100 handle this or do I need to
switch to giga-something networking?) (currently my mac watches mythtv
over my wireless .g network and it works great!)

Is another solution to have this storage system connected to the
backend and have the other computers on the network access it by
network? (ie. the heavy loads will be directly through a sata or scsi
connection, whereas the light loads will remain on the network)

Does any of this make sense?
Any advice, direction, tutorials, RTFM (with a link to where the FM
is!) would be fantastic.

thank you kindly,

Re: [mythtv-users] OS X & MythFrontend 0.18.1 with plugins

[David Snider]

Thanks for downloading the binary.  I'm very interested in your  
feedback, if a build doesn't work, I'll want to pull it off the site..

As for me, I use mplayer, but until recently, DVD VOB's with AC3 had  
noticeable static feedback.  However, I found that you can download  
the CVS version of mplayer and it compiles just fine on MacOSX.  It's  
much faster than previous versions (Uses the CoreVideo services now)  
and there is NO static feedback.

I don't know this for certain, but I installed mplayer first via fink  
(to get a lot of the dependencies, may or may not have been  
necessary) then downloaded the CVS version and compiled and installed  
to /usr/local/mplayer instead of /usr/local/bin.

My Video player settings are setup as /usr/local/mplayer/bin/mplayer %s.

My .mplayer/config contents are:
subcc=1
fs=1

I like the closed captions and full screen mode...

Never used Xine on Mac, found a link to a binary on Wikipedia, but  
could never get it to download.  To be honest, I just use the Apple  
DVD Player, no offense to the developers of MythDVD.

I didn't say "missing recordings;" I said "missing videos."  Anyway,
I don't see the relevance; something had to record them, so what does
it matter what I call them?

I'm not doing that.  In the SVN at least, when you fire up "Watch
Videos" you get complaints about all the videos that are known to the
backend database but can't be found in the local filesystem.  Only a
common mountpoint can cure that problem AFAICT.

Try setting up a time in the "schedule manual recording" screen.  I
think you won't be happy.  Even in other screens, don't you expect the
big "select" button in the middle of all the arrows to be able to set
a checkbox?  Does it really make sense to you that pushing the
"rightarrow" button sets it and the "select" button dismisses that
screen?

I have a wireless keyboard/mouse for that ;-)

You're welcome; I was very glad to be able to make a contribution.

I don't think the video manager is what I want.  First of all, it's
apparently only designed for using an external player, not for playing
within the MythTV frontend.  Secondly, the video manager seems
completely messed up when you are running multiple frontends, since
they are recorded in the global backend database but only referenced
relative to the frontend's local filesystem.

[mythtv-users] Watch Videos

[David Abrahams]

It appears that the Watch Videos feature only looks on the frontend's
local filesystem for files, but a record of all the recorded videos is
kept in the backend's database, causing it to complain about all the
missing videos that were recorded on other machines every time I fire
it up.  Is this feature only supposed to be used with a
network-mounted disk, or... ?

Thanks in advance,

I'd be happy to; I have one that's presently gathering dust.  What's
your address (offline, if you prefer)?  The more muscle we can put
behind Mac development, the better, as far as I'm concerned.

AFAICT, there's no processor-specific optimization in playback at all.
So if performance is bad on PPC/Darwin, it's probably bad (compared to
what's possible) on x86/Linux as well.

Ouch, really?  Not good news for the MacOS folks.  I wonder what about
the MacOS frontend is sucking so badly?  I am running a
frontend/backend combo on a 1.42 GHz Mac Mini (admittedly it could
stand a RAM upgrade from 512M to 1G, but I don't think that's the
issue) and I see a *lot* of beachballs.  Maybe I'd be better off
buying a cheap linux box, but I really like the "just-works appliance"
nature of the Mac for this purpose.

Any idea how I can find out what the problem is?  I don't imagine
profiling will make a huge difference in such a highly threaded
application.

Why not?

Can you explain why you are pretty sure of that?

[mythtv-users] Universal Remote Code for Leadtek TV2000XP Remote (OK, a little off topic)

[David Krainess]

Hi all,

I figured if anybody knew this, it would be in this
group.

What is the code to use to setup a universal remote
for the Leadtek TV200XP CoolCommand remote IR
receiver.  

I.E. the Hauppage Gray remote is "0081" for the signal
protocol.  Does anybode know the Leadtek one?

Thanks in advance.

I've seen that No PIDS set message from time to time when I've been
fiddling with my channel setup. I think it's related to the starting
channel - ie the channel that mythtv initially tunes to.  As I
understand, if this channel is incorrectly setup, or not broadcasting
at the time, then mythtv fails rather ungraciously.  You can fiddle
around with the starting channel using the channel editor but I've
never been very successful with making this work - for some reason the
change doesn't alway stick.

My advice would be to delete all your channels (by letting mythtvsetup
remove them as it starts) and redoing the auto scan.

BTW you can get the exact parameters for your transmitter for the
autoscan from the channels.conf file the tzap produced just look
across the row for BBC1.  I only had to do a single scan for the
Crystal Palace transmitter, to get all available channels, and More4
and ITV4 added themselves automatically,without scanning, when they
came online.  YMMV.

Hope this helps.

I am still not sure why it doesn't like the dual recordings (did you
