I posted this on the Knoppmyth forums (and got a complaint on why it was an
installation issue) http://mysettopbox.tv/phpBB2/viewtopic.php?t=5955

I have a 3 month old installation that was working well until I allowed it
to fill the disks. Once the recording section filled it started getting
errors and the log files filled the root partition and it was all downhill
from there. Apparently there were some shared blocks that e2fsck wasn't too
happy about and I was never able to get it clean. So... I appear to have a
good LVM partition of videos but I need to rebuild my root partition. I'm
afraid to just let it do an install and have it roach something that I will
need or init the /myth directories. is there something here (which I
haven't been able to find in my search) that describes this type of
recovery? I've got 550gb of videos I'd like to salvage if possible. my
other choice is to swap in a virgin drive and rebuild on that and then copy
the root over onto the bad partition once it's up and running. I await your
collective words of wisdom...

also

yeah, hda1 is totally toast. it filled and the fsck found a bunch of
problems including some duplicate inodes and it segfaults now when I run it
on the partition from the Knoppmyth CD. The /myth/tv partition (lvm) filled
but still had a few megabytes. I made the mistake of trying to delete a
known bad recording through mythweb and it hung, I couldn't even ssh in and
when I rebooted, fsck roached hda1 as it came back up.

So, I assume that from your comments/solutions that the database is on the
root partition?

is there enough info in the .nuv files to recover the names/dates of the
recordings or will I have to sort them and manually fill them back in?

none of it is irreplaceable. i'm sure I can regather all the old repeats
I've been collecting to archive. I just wish I had had more time to write
them to DVD since I had just gotten Martin's MythBurn scripts working. I
wish it had deleted/expired some of the old recordings and freed some space
but it didn't.

out), Sempron 2800+, 2Gb RAM, 600Gb HD

So, can anyone give me a possible recovery method with the root partition
totally roached? An upgrade install was what has been suggested in the
forum using the LVM instructions which seems to just update the root
partition but then I have the issues with recreating the database...

If you want DVD-format recordings, why do you record in a non-standard
DVD-resolution. Standard DVD-resolution are e.g. 720x480 for NTSC and
720x576 for PAL.
2G for 30 minutes seems a bit overkill. I get about 2G per hour and
that's nice quality. I doubt your cable company sends out an analog
signal that's the equivalent of 8Mbit/s digital so I'd lower that. Do
some testing with different bitrate settings.

As for commercial detection. Either someone would need to setup a
small database where for each type of CPU the time to commercial-flag
a 30 minute recording takes or you'll have to hope someone is using
the same CPU as you are. Again, do a test yourself.

 I would rather have a higher quality recording and buy another hard drive, 
 but I don't want to have
 a bit rate that is way to high. My concern is really getting High quality 
 recordings to put on DVD

 I want them to be able to play on anybody's set top DVD player(mom, and

VHS-recordings have an even lower resolution than TV so you can up the
bitrate all you want, it won't make it look any better.

	Whatever you do, don't make the extremely common mistake of 
thinking that VHS having 240 lines of resolution means that a 320x240 is 
an appropriate capture.  In analog video land, lines of resolution is 
related to *horizontal* resolution, not vertical.  There's other stuff 
involved, but reasonable (NTSC) figures are:


S-vid: Potentially 720x480
Composite: 480x480, *maybe* 540x480-ish
Cable: See Composite (same thing, only RF-modulated)
VHS/8mm: 352x480


	Bitrates are another matter... For captures, the quality is 
primarily noise dominated.  Commercial DVDs are in the 4-5 Mbps range, but 
they've got the advantage of nice, clean sources.  Lower resolution and 
increased noise seem to tradeoff for broadcast captures.  A 480x480 at 4-5 
Mbps is probably pretty good.

Oh, I played with the whole display size thing until my fingers bled.
100dpi just seemed to move things around the screen a bit, but not

So he's saying he doesn't want to waste recording time with MythTV trying to record The West Wing from Bravo when the channel is actually Hallmark. My Comcast program guide showed the Comedy Central programs for all day, even though we only had it after 6, and I'm assuming he has a similar problem. So Myth would think The West Wing was playing on 61, but really it would be Little House on the Praire or some other equally boring Hallmark channel show :)
That being said, I'm a lurker who hasn't yet put together my HTPC and thus don't have any experience in Myth, so I'm just clarifying (I believe) what he meant to ask. He only wants to record from Bravo after 5:30 basically.

Mine works fine over 802.11b. I have mythstreamtv
playing smoothly over my older Dell Axim PocketPC. Just
make sure to use the lowest settings and increase until you see
problems, but I normally use lowest settings, which is still fine for
watching. For home WAN, I too use the fastest settings.
I have tried this directly over my home WAN and also from
work. (DSL to DSL then to my PPC hooked up to work
network). I've even tried it from a dailup
connection. While extremely choppy and totally unwatchable,
it is cool to tell someone in timbuktu to dialup to the internet and
point the media player to my IP and they can see a picture or two of
what I am watching. Show you folks your not

I have some fir trees between me and the transmitter.


MythTV receives all but one mux without problems, but one is problematic 
to tune into (lock keeps breaking) and channels associated with tend to 
be the first to break up


If all muxes are being transmitted from the same transmitter, why should 
one bundle of channels feel like it is coming from the moon ? Are muxes 
simply s/w abstractions or do they correspond somehow to physical 
divisions in the h/w - i.e. is my problem mux maybe being pumped out at 
a lower power than all the others etc...


Would a booster be likely to solve the problem, or do I just live with 
it - they are tall fir trees and not mine :-)

Re: [mythtv-users] Transcoding to 480p

2005-09-08 Thread Brian McEntire

Thank you Robert!

Can anyone add on to this? I'd like to use mytranscode or nuvexport. I
couldn't find a man page for either, but if someone will point me to
docs, I'll gladly read them.

I'm trying to transcode 1080i and 720p down to 420p (852x420 pixels). I
would like to keep the bit rate as high as necessary to keep as close
to the original quality as possible but granted, throwing out 1/2 of
the information which won't display on my TVs native resolution anyway.

Can anyone recommend a command line? I wanted to do some initial tests before setting up any automatic transcoding.

Is MPEG4 considered to be higher quality or easier on decoding for
playback compared to MPEG2? I'm much less concerned about encoding
performance/time; playback quality and playback resource usage or my
primary concerns. If possible, it would be great if transcoded HTDV
(down to 420p) plays reasonably smoothly on a 1.6 MHz P4.

[mythtv-users] Odd pauses when starting recorded shows...

2005-09-08 Thread mythtv

Now that my Myth box seems to be fairly stable, I'm slowly starting to
migrate recording shows off the Tivo and onto the Myth box. As I'm
actually using Myth a lot more, I've noticed a few problems...

1) When I select a recorded show to play from the menu, on about 20% of
them, the screen goes black and there is no sound, it sits there like this
for anything from 10-45 seconds and then the show starts and plays as
normal...
I've run the database check and it's all fine and playing the files over a
samba share is OK too. Playing videos in MythVideo has no problems...

2) Scrolling up and down the recorded shows menu, occasionally pauses for
a few seconds, with what sounds like harddrive thrashing about, before
continuing as normal, this is a minor problem, but it's SOO
annoying...

3) When using the 30 second skip, it skips and then kind of does slow
motion for about 1 sec or 2 and then plays properly. Is this normal? or is
there a problem? It's annoying after using the 30sec skip on the Tivo for
years...

Any ideas? It's really impacting the WAF...

Lee

1. Not all muxes are transmitted with the same power. There's a
website somewhere that tells you the power of each mux for each
transmitter (should be linked from the freeview website).

2. The sensitivity of your aerial is not constant across all
frequencies. You can buy aerials that give you excellent reception for
certain frequency bands (you'll need to figure out which one is best
or your transmitter) or you can get a 'wideband' aerial that will give
you average reception over a frequency range that should cover any
transmitter (this is what most standard retailers will sell you).

Chances are that what you are reporting is due to '2' above. The 'bad'
mux is almost certainly on the highest or lowest frequency of the six
muxes for your transmitter, and you'll almost certainly be using a
'wideband' aerial. My suggestion would be to either buy a higher gain
'wideband' aerial or (probably better) buy an aerial that matches your
required frequencies.

Re: [mythtv-users] Off Topic - DVB-T, Muxes and reception...

2005-09-08 Thread Michael Cowell

If the muxes are broadcast at different frequencies (which they would 
be), then it is quite possible, even probable, for the SNR (signal to 
noise ratio) to be different for each.


The channel between you and the transmitter (which includes the trees) 
would have a different response for each carrier frequency. The 
amplitude / phase response could be very different for different 
carriers. If something between you and the transmitter was, say, 
resonant at a particular frequency, that would cause a lot of noise on 
that particular frequency, but little on others.


A booster cannot change the signal to nosie ratio - only boost the 
amplitude of both. However, that may solve the problem. It all depends 
on the amplitude that your tuner needs to be able to effectively 
demodulate the data signal from the carrier. If all the other 
multiplexed streams are received fine, then you should make sure that 
the booster you picks leaves them alone.


Now, unless you buy a good one you're probably going to *decrease* the 
SNR for most muxes. So if they are already somewhat prone to error - I'd 
be wary about adding more hardware between you and the signal.


I'm not sure how fir trees affect signals at the 100s of MHz range - so 
I cannot comment on whether they are the likely cause of your 
interference, or whether the problems you are having are indicative of 
the channel in your areas, as a whole. Maybe someone in you area could 
provide good advice on what they had to do to get a good signal.


Hope that was some help,

Michael

Each mux is transmitted from a different tranmitter. These tranmitters may
well be in the same place, but are seperate physical bits of kit.
They don't necessarily all point in the same direction or run at the same
power. And this type of problem is fairly common with old analog antenna
setups.

Recheck all the connections as a first move.
Try to get the antenna higher, this usually help.
Try moving it to left/right and see if that helps.
Finally, a booster may well help, but isn't guaranteed.

Just a quick follow-up to my earlier post. You can see the gain for
different aerial groups on the follwoing graph
http://www.wrightsaerials.tv/Articles/img/fig%201, Obviously, higher
gain is better.

The power of the different muxes is given on this page:
http://.dtt-tx-info.org/change_tx.htm

As you can see, muxes C and D are transmitted at half power compared
to the rest. And since mux D is at the highest frequency i'd guess
that the one you're having problems with, right? (Mux D shows TMF, The
Hits, Ftn, etc).

Re: [mythtv-users] How do you adjust font sizes?

2005-09-08 Thread Adam Bodnar

Something I've never quite been cleared on, but for NTSC svideo is it
better to run the screen resolution at 1024x768 or 800x600?

I've finally configured X to 100dpi and am slowly resolving the issues
to fixing the font size as well.

  (Hint, set DisplaySize in xorg.conf or give -dpi 100 to X server.)
 
 
 Oh, I played with the whole display size thing until my fingers bled.
 100dpi just seemed to move things around the screen a bit, but not
 actually fix anything. 75dpi (which was the default when I installed
 KnoppMyth R5A16) was almost there, but adjusting that .xml file made it
 perfect...
 
 As usual YMMV...

I've noted a difference between reception issues between different
DVB-T cards. I started off using Hauppauge Nova-T PCI cards which
caused me to keep going back to the aerial when a couple of channels
(on multiplexes 2 and A) would break up a lot during recording/live
TV. The other day I installed another slave backend with a pair of
KWorld DVB-T Xpert PCI cards, which, using an older booster and
daisychaining the aerial feed, gave absolutely no problems and tune
between channels extremely quickly (esp in Kaffeine). The channels was
also very quick in Kaffiene compared to the Myth scan.

I would therefore try a booster first of all, and then if problems
persist, try to borrow a freeview box to see if it's really the
reception or the card that it causing the trouble.

Make sure that the DK grabber supports specifying the number of days
to fill (use -1 instead of 10 to fill all days) and make sure the
xmltvid for the new channels is present and matches the one the DK

 Video card with S-vid out. Use an S-vid-RCA converter and a stereo
 mini-to-RCA cable for audio. Either run these direct to the aux-ins of
 your TV, or send them into an old VCR and then to the TV through coax.

For best picture quality, I'd recommend using a direct S-Video
connection to the TV (or video and a S-Vid connection from VCR to TV)
from a PVR-350. However, my experience using my Pundit-R with TV-Out
is that the quality is really quite good (using at moment until I try
out the vastly improved XV support on my 350) and that's integrated
video. Users with Geforce MXs tend to report the same results when

 Its generally a bad idea to use multiple ir devices on a single machine.
 
 It is possible to chain lirc (have two instances of lirc - one for receive

 My suggestion would be to get a IR device that receives and transmits (I use
 the USB UIRT www.usbuirt.com) which allows you to send and receive with the
 same device and Lirc Instance. Once you have your device - they generally
 work with ANY remote - use irrecord to setup the remote of your choice.
 
 If all your interested in receiving IR commands - your audigy is probably
 supported (do a google search for audigy LIRC).

Hello David et al,

I'm setting up a new MythTV box and I notice a patch just got submitted
to Lirc for the USB-UIRT product.  It appears this device supports an
external emitter.  I need to be able to control two separate digital
cable tuners of the same model.  Would I be able to accomplish this with
the USB-UIRT and an external emitter like the following one?
http://www.smarthome.com/8171.html

If both cable boxes are Sci Atl 3250 (non-HD), how would Lirc know which
one is which?

I was planning to get a Hauppage PVR-500, but since my system has plenty
of PCI slots, I could just get two PVR-150's with the integrated IR
receiver and blaster.  Would this work better in my situation?

Thanks.

I don't have specific experience with medical software, but I've had a 
few PDA's.  And my doctor uses a PDA to look up various references and 
also to write scripts (they print out via WiFi on a printer at the 
nurse's desk).  I believe his was a PalmOS PDA last I checked.  I used 
to prefer Palm but I've come to love my PocketPC 2003 PDA.  There is 
lots of medical software available to install on PDA's.  PocketPC (or 
Windows Mobile I think they call the current version) is a bit more 
flexible and has more software available for it.  PalmOS used to rule 
but has languished in the last few years and lost a lot of marketshare.

When I setup my PVR-500 initially, I had a similar problem.  When I
setup the first PVR-150, and told it to use /dev/video0, and for the
second PVR-150, to use /dev/video1.  With it configured this way, it
acted kinda like it knew I had two tuners, but only one was actually
usable.

As it turns out, on my system I needed to tell it to use /dev/video1
and /dev/video2 for the two tuners in my PVR-500.

I think maybe /dev/video0 was being claimed by the NTSC tuner of my
HD-3000 card.  Since I never use my HD-3000 for NTSC, it did not
initially occur to me that I needed to skip /dev/video0.

Re: [mythtv-users] WinTV-PVR-500

My backend logs are /var/log/mythtv/mythbackend.log? Because if they are I don't see a single thing about AutoExpire in there at all.

I'm pretty sure my HD is fast enough, it's a brand new seagate (This 7200RPM, 300GB drive features an 8MB cache and whisper-quiet motor). How can I check the CPU during playback?


By the way my IVTV version 0.3.8 compiled on the 5th on this month :)

Does the backend report 2 recorders? And the stuttering; it's more like stuttering video, not audio.What type of system are you using? How's the CPU-usage duringplayback. Is your HDD fast enough? During LiveTV you write and read to
the same file so that might cause a bottleneck.Check your ivtv-version (via dmesg or modinfo on the ivtv.ko module).N.

[mythtv-users] OT: enabling xfs in Fedora Core 4

2005-09-08 Thread Frank Lynch

Hi Folks,
This is completely off topic, but given the number of fedora users on
this list I figured I'd go ahead and ask.

I built a FC4 system, but forgot to enable xfs at install time. Ext3
isn't cutting it for storage of large media files. So I'm wondering if
it is possible to enable xfs in Fedora Core 4 without having to go
back and do a complete re-install?
I imagine that it must be possible to download and install the
relevant kernel modules and utilities for xfs?

Can someone point me at rpm's or details on how I would do this using
yum. I really don't want to have to rebuid this machine from scratch.
thanks in advance for any advice/tips/suggestions,
cheers,

Re: [mythtv-users] Crackling and popping in non-PVR analog card -- I think I can say it's MythTV's fault

2005-09-08 Thread Sérgio Gomes


Hello everyone!

I have finally found the problem!

I did a little experience: I enabled the AC97 soundcard in my 
motherboard and connected the output of the TV card to it instead of to 
the Audigy. No more crackling! However, I noticed the volume is way too 
high! The TV card seems to be outputting sound at a very high level. The 
Audigy tolerated this, but not my AC97 card. Not very serious though, 
I'm getting an attenuator to solve the problem.


The high levels were however not the problem, since the crackling only 
happened in MythTV and not when I recorded TV sound in other programs.



So, the crackling I experienced is probably MythTV not liking my 
soundcard (Audigy 2, emu10k1 kernel module), since in all other 
programs, and all the playback and recording experiments I did there was 
never a crackle or pop. The emu10k1 factor is also consistent with 
Michael Cowell's setup, who posted his similar problems. It must be 
something in the emu10k1 driver that MythTV doesn't like.


So, what I can say is, if you have a TV card with a dongle cable to 
connect to a line-in, don't connect it to an emu10k1. MythTV won't like it!


Thanks for bearing with me!

Download the XFS tools, install them, and then reformat the video
partition using mkfs.xfs, and you should be good. I note from Jarod's
FC4 guide he now prefers using JFS though.

It's enabled (you can mount an XFS partition if you somehow get it).
You just can't create one, you need to install xfsprogs RPM for
that. Then you'll see mkfs.xfs, xfs_check, xfs_grow and all the

[mythtv-users] Just moved to Time Warner cable...

2005-09-08 Thread Tony Paterra

Hey all, I had my myth box up and running quite well and now I have
moved and switched cable providers...  I have a PVR-350 running with
MythTV 0.16 on Slackware 9.1 and Time Warner digital cable as the
source.  For the time being I am not putting the digital cable STB in
the equation, I just have a splitter that is separates the Myth box
and Data Direct is giving me only the Cable program guides, not the
full 1000 digital cable ones.

Now for the problem...  I went into myth setup and cleared out my
configs (which cleared out the old channel database for me) and re-ran
mythfill database to get everything I needed for the program guide.
The behavior I'm now noticing is that my program guide works as
expected, but that I am getting either very fuzzy channels or complete
static when trying to watch live tv.  I have tried going back into
setup and changing the frequency table settings to us-cable, us-bcast,
and us-cable-hrc to no avail...  Any thoughts?

Thanks in advance,

 Off the top of my head, I'd say you want to set the backend up as a slave,
 set the IP for the current backend as master, mount your nfs properly and
 set up the proper directory structure, put the cards in the front end and
 configure them, and make sure the boxes are checked correct to not allow

 My question is why you'd want to do that?

Thanks - thats what I thought would be the way, nice to hear confirmation!!

As to why? The EPIA card is considered by some as underpowered as a
frontend only - the fact that it has a mpeg2 hardware decoder is what
saves it!! Asking it to transcode etc as well as handle the realtime tasks
of displaying video without glitches I think is asking for problems. Quiet
is one of the main requirements, hence diskless and reduced CPU load will
help here as well.

My server on the other hand has over 800G of disk, 1G of RAM and a 3G CPU

RE: [mythtv-users] CD Ripping FC4 Now working

2005-09-08 Thread David Maher

CD on my FC4 backend ripping has suddenly started working. I had given up 
trying to fix it, but it must be like a lot of things in life - ignore the 
problem and it goes away.
I have been fiddling around with my mythbackend a lot recently, getting a usb 
dvb card working etc, so I have made a lot of changes to the system.
The major changes are:

Compiled and Upgraded vanilla kernel 2.6.13 (because it had twinhan dvb-usb 
support)
Upgraded Myth to current CVS (7215)
Yum update

I haven't upgraded either of my frontends yet, so I'll be a bit more scientific 
about this when I do upgrade them and find out what fixed the cd ripping.

But at least we know it can be made to work!

[mythtv-users] Prompt to switch to record mode in live TV kills frontend

2005-09-08 Thread Matt Goebel

Whenever I am watching live TV and I get prompted that Myth wants to use the 
live
tuner to record and I don't chose an option (defaults to record and watch as it
records) it causes the frontend to crash.  It also causes that tuner to no 
longer be
available when I restart the frontend.  The backend still chugs away, it's just 
that
everything that gets recorded by that frontend just ends up being a 0 byte nuv
file and it never lets me use the tuner for live TV.  I have to stop the 
frontend
and restart both the master and slave backends before everything works again, 
then
delete the blank recordings through the frontend so they'll record again.  I 
haven't
tried this in debug mode yet but there are no errors otherwise in a log file I 
can
see.  Obviously this is quite the hassle.  Has anyone seen this and/or fixed 
it?  If
it makes a difference I have a cable box controlled though my serial port and 
the
external channel command I compiled from the contrib directory.

Re: [mythtv-users] Non-recording master backend

2005-09-08 Thread Todd

I don't think an EPIA will work unless you are using an MPEG capture card. 
It might work, but it will be very close.  I am running an M1000 (neiman) as 
a front-end + back-end with no capture.  It runs at 40% CPU usage playing 
back, and takes on transcoding jobs from other capturing backends with it is 
bored.  (my other backend are frontend+backend and is capturing while I am 
watching (Primetime), it is nice to have the recordings transcode when I go 
to bed...yes, to watch even more tv if I want!)


You might consider Using a CF to IDE converter (the PC will see it as any 
normal HD) for the base OS to load, and NFS mount /var and the other high 
transaction, high volume directories.   That keeps things simple, but also 
silent.  You don't want to write to CF too much, it supposedly fails much 
sooner than an HD.

Re: [mythtv-users] WinTV-PVR-500

2005-09-08 Thread Joe Votour

Check that the ivtv driver detects your PVR-500 as two
PVR-150s.  Check that you can get data from both
tuners by doing a cat /dev/videoX  test.mpg, where
X is first 0, and then 1.  If not, then it's an ivtv
problem.

Also, check that in the MythTV setup that you used
Tuner 0 for both /dev/video0 and /dev/video1. 
Despite the fact there is a Tuner 1 entry, it isn't
used with a PVR-500 (because the PVR-500 is seen by
the ivtv driver as two PVR-150s).

Can't help you with the LiveTV issue.  I rarely get
pauses when using it, and when I do, they're once per
half hour, or even once per hour.

[mythtv-users] Mythgallery directory permissions when using NFS

2005-09-08 Thread CTD

Not sure if this only occurred for me or if this is due to some other 
system config issue.  There was probably some simple way to overcome 
this, but I started down this path after trying many others.  This way 
seems to work, but I am curious what people with more Linux experience 
have to say.


Setup:  My frontend is on an xbox running xebian with /mnt/store mounted 
to an NFS on the backend.   Mythgallery  on the frontend  points to 
/mnt/store/pictures.


Issue: thumbnails cannot be generated by mythgallery due to permissions 
on .thumbcache directories.


Background:  I knew from previous posts that mythgallery needed write 
permissions on the base directories.  I could manually do this every now 
and then, but I wanted this to be somewhat automatic for new picture 
directories created on backend.


My Solution:
1) Setup directories on backend per:
chmod 0777 +R /nfs/store/pictures
chown +R mythtv /nfs/store/pictures (not sure if needed or if any 
non-root user is ok)
chgrp +R mythtv /nfs/store/pictures (not sure if needed or if any 
non-root user is ok)


  Note: Hate having permissions of 0777, but unsure how to coordinate 
users on NFS client and server.


2) Ensured the following script is run every time my frontend is started 
which ensures that any new picture directores created since the last 
bootup have correct ./thumbcache directories.


#!/usr/bin/perl

# Purpose: Create needed thumbnail directories used by mythgallery.
#  This is done due to apparent issue in mthgallery on xebian
#  where the .thumbcache directories are created with the incorrect
#  permissions. #
# Functionality: This script will recurse the mythgallery picture directory

[mythtv-users] SLOW channel changing inLiveTV- 6 question, 30 second survey

2005-09-08 Thread Buzz


Hi All!
To guage an interest in LiveTV usage/etc, I have created an EXTREMELY QUICK
survey. It's only 6 questions, and does not require any registration or
anything personal.

Even if you have already commented to the list on this, your response is
really appreciated.   After-all, I'm not going to try implementing something
if people don't actually want it.   :-)

Yes, I'm serious, and no I'm not affiliated with 'free surveys' at all, they
just happen to do free online surveys  :-) thanks.

[mythtv-users] Some confusion on record weekly schedules...

2005-09-08 Thread Alex Brekken

Hey guys, I've got what might be an easy question regarding Myth's
handling of weekly recording schedules. I've got a record
weekly schedule set up for the new Battlestar Gallactica series on
SciFi every Monday night, 10:00pm CDT. I've had this setup for a
few weeks now, and it works great. Today, however, I noticed that
SciFi also has a Friday night at 9:00pm showing of Battlestar, so I
setup a record weekly schedule for that listing as well. I've
since discovered that the episode that shows on Monday night is a
repeat of the previous Friday night, or at least that what it looks
like so far. Nevertheless, I opted to keep both schedules in
place, figuring that even if they are the same episode Myth will sort
that out for me and only record one.

Looking at my schedule recordings page on Mythweb, here's what I
see: for this Friday evening (tomorrow), Myth is NOT going to
record this episode and has a code of L next to the showing, which
apparently means it will record this showing at a later time
instead. For Monday, Myth WILL record that showing of
Battlestar.

Now I fully understand that Myth should only record 1 of the 2 showings
since they're the exact same episode, however I can't figure out why
it's electing to record Monday's episode instead of Friday's since
Friday is an earlier date. There's no other recording happening
on Friday at the same time which would interfere. (I've got dual
tuners, so that wouldn't matter anyway) What I would expect to
see is that Myth would record Friday's episode, and skip Monday's with
an indication on Monday's schedule of P for previously
recorded.

Does this seem like a problem to anyone else, or am I just misunderstaning how the behavior is supposed to work?

With the PVR-350 at about $160 these days, to me .. that's like buying
a ~$100 TV-out card, vs $40-50 for a cheapo TV-out vid card.
 

Not to mention you get more from the cheapo TV-out vid card:  OpenGL, 
ability to do resolutions greater than standard definition, XvMC support 
(which is very nice for HDTV), VGA/DVI output, progressive output,   
Of course, XvMC assumes you buy an NVIDIA (since ATI's drivers /still/ 
don't support XvMC)...

Question 6 doesn't make a lot of sense to me, as worded. How often
would I use LiveTV much more?

In my case, it would not at all affect how much I use LiveTV. But
then, I don't find the delay to be too long.

(Notice also the typo on Question 5; it should too)

Re: [mythtv-users] Automatic deletion on drive fillup doesn't work

2005-09-08 Thread chris

 I have 650GB on my master backend shared out the sole Myth slave
 frontend/backend
 via NFS on which I keep all my recorded shows.  A few days ago this filled 
 up.
 Instead of automaticly deleting older or lower priority shows, as I
 thought Mythtv
 was supposed to do, it just continued on recording shows of 0 bytes.

Just a hunch: although you specify the remaining disk space in 
gigabytes, some filesystems reserve a certain percentage of the disk 
for root's exclusive use so that logging and daemons would continue to 
work if a run-away user process tried to fill the filesystem.  From a 
user's perspective, df would show lots of remaining space (typically 
5% for ext2/ext3) but writing data to files would fail if it resulted 
in an allocation request.  If that percentage is larger than the fixed 
size you specified then the auto-expire routine would never be 
triggered.

I've had a few people tell me Q6 is too biased, so please answer 'other: no
change' or similar if you find any of the other answers unacceptable. I
will take this into consideration prior to posting the summary.   

Oh, and please ignore the minor typo in Q5.   :-)   

I can't modify the survey after it's started, unfortunately.

Buzz.
