[mythtv-users] sky plus navigator remote, which IR receiver?

[Ashley Bostock]

I've recently brought a sky plus navigator remote (one with the
keyboard inside) and want to set it up to be used with my mythtv box
(pundit).

What's the best IR receiver to get or build? I dont mind which. Any
good tutorials ppl can recommend - I found loads on google, but I
think I need to make sure it supports RC6 codes?

Thanks,
Ash

[Ashley Bostock]

Just a couple of quick gentoo points:

You can put:

LIRC_OPTS="--with-x --with-driver=hauppauge --with-major=61
--with-port=none --with-irq=none"

In to /etc/make.conf and then just run:

emerge lirc

Instead of having to type all that each time.

> make menuconfg
> genkernel all

That can also be simplfied to just:

genkernel all --menuconfig

Hope that helps.
Ash.

[mythtv-users] Help with recurring problem

[Ed]

I have Myth .17 installed on FC3 with 1 pvr-250. Everything seemed to 
go good. I was all up and running with no problem. I put some shows in 
to record and rebooted the system a few times and now when i go to 
watch live tv i will get picture and sound for about 2 seconds and then 
the screen will freeze for 10 seconds and say there was a error with 
the video, or just lockup the frontend. This has happened a few times 
now, and i found that if i deleted the database and recreated it, it 
would be ok again for a little bit(not sure what this has to do with 
any thing).  Here is the output when i run the frontend from a 
terminal:

Re: [mythtv-users] MythTV in New Zealand

Ok - so the opposite works also, clear the database out and then strip 
mr.geek.nz from the
xlm and it loads fine and displays in the scheduler. Just have to remove 
this each time, why does he
have this included as it must be breaking his myth setup also?

Easy enough to strip this out using sed though

No, I have changed the XMLID of each channel in the channels table of
mythconverg to read TV1.mr.geek.nz, and so on. Oh, and you'll need to
use different sources for TV1/2 and 3/4 as Saturn and Sky don't seem to
carry certain channels, I can't tell you which is which as I'm not near

I've found the listings from here to be pretty reliable apart from a

You could try valgrind.  I valgrind-ed our largest product at work (a
few hundred thousand lines of C++) which nothing has ever been able to
do before.  It didn't run very quickly but it did work and I found all
sorts of nasties.  Unfortunately I'm not sure valgrind works very well
with threaded programs.

It should work fine with threaded programs. The CVS code might be
better as it uses the system threading library instead of replacing
it.

Actually, as long as it's possible to create several transcode profiles
one could just have the transcoder pick the profile which is closest
in size without going over, or somesuch.

I don't think of this as scheduling jobs so much as "Do this at any
convenient time, but not before time X" (or more simply, not before
a certain age)   There are a few other things you might do on this
formula, such as turning on autoexpire.

If transcode didn't take so long, the ideal arrangement for delayed
transcode would be to predict disk space requirements, and instead
of deleting shows, transcode the night before to clear enough space
for the rest of the day.Of course if new programs are requested
you would still run out and have to expire.

With HD, though, we now see two purposes in transcode.   The traditional
one, to save space, and a new one, to scale down for easier playback.

thanks again
i actually do

make menuconfig
cp ,config /etc/my-very-own-config.conf

i'm sure there is probably a better way

[mythtv-users] Resolution to stuttering on final 10-15 seconds of playback?

[Neil Bird]

  I've only just noticed that my 0.71 is doing this odd 
stuttering/freezing during the last 10-15 s. of playback (usually don't 
get that far).  Again, it's not that important, but it is a little annoying.

  Has there been any consensus as to its possible cause?  I didn't see 
anything turn up.

now at this pint i'm going to place foot in mouth
but the implication of your email is that the sky+ remote generates RC6
i was not aware of that - in fact i thought it generated somethink akin to 
IRDA
but please correct me if i am wrong (really - no sarcasm implied)

  Even with 'All' filters enabled, I don't seem to be getting much 
luck* flagging commercials (for Sky One, so far).  The odd way Sky run

 anyone out there find it's working OK for them?

  Not yet checked 'All' on a terrestrial station.

Is it possible to capture DVB with a different resolution than the

[mythtv-users] [Improving] The Current State of Myth -> DVD

[Brad]

I would actually like to see a much simpler version of this idea. I 
think it would be just as good, and probably a lot easier to 
implement, a solution that simply allows a user to select recordings 
(and perhaps files in the Videos section too -- to account for 
recordings converted with nuvexport) and have them burned to a 
data-dvd... all using only a remote control and the MythTV UI. It 
would be nice, perhaps, if the process for later playing a movie 
saved to a data-dvd in this manner were made a little easier too... 
thereby allowing a user to save recordings to a disc and play them 
later on their MythTV system, all relatively painlessly and using 
only the remote control.

I think the eventual goal of burning dvd-player compatible recordings 
is a good one, but the problem is currently sufficiently daunting to 
cause people to stop before they get started. Maybe a "baby-step" 
such as this could be a good interm goal?

Just my 2 cents.

If you get the 250, yes, you'll need a way to get the picture to a tv

Also, if youre going to use the MythTV box for gaming and watching
DVD's the 350 will not help you. I made the mistake of buying a 350
thinking I would be covered, but I was wrong.
From what I have read since I bought my 350, it's a tradeoff, the 350
output gives you great Standard TV out, but you cant play games or
watch DVD's because the framebuffer is too slow. A video card with
tv-out does not have as great of a picture on the TV, but you can play
games and watch DVD's.
The framebuffer is plenty fast for DVD- and mpeg4-watching as long as you  
use the ivtvdev X driver and your CPU can keep up with scaling and stuff.  
Playing games is trickier, although I have never tried it myself (except  
the occasional UAE session).

Is this really true?  From what I can see, most flat panel
HDTVs (LCD/plasma) are 768 or 788 lines (few 720, 1024, and 1080).
Most CRT HDTVs still convert 720p to 1080i.  Only microdisplay
(LCD/DLP/LCoS RP) HDTVs are at 720 lines with Sony the major exception
at 788 lines and with new 1080p sets coming out this year.

I have the too. I'm on gentoo/xorg-6.8.2(and ++ unichrome and a few
other patches I think. It's a ebuild at boom.kalf.org/epia)

You'll most likely be able to ssh in and kill X. (X is the oen using up
100% CPU) for some reason.

After getting the ebuild for Xorg+unichrome, I can say that it works.

YOu still can. I had that same scenerio. Fluxbox (okay.. very minimal X)

Try getting it patched for unichrome.

Re: [mythtv-users] Commercial flagging in the UK (Sky, specifically)?

[Robin Elvin]

I don't get anything flagged properly on UK DVB-T with Myth 0.16
At best I get about 50 markers in an hour program which means it's being way too
sensitive. I don't see any blank frames, aspect switches or disappearing logos
at the start of ad breaks so I presume this sort of foils the detection code.
The reason I'm getting so many is probably due to scene change detection but
I'm only guessing.

Anyone got commercial flagging working in the UK?

I have a Mitsubishi DirecTV+ receiver that has a D-VHS port on the back.
It looks like a firewire port. The manual says something about the

Re: [mythtv-users] [Improving] The Current State of Myth -> DVD

[Cory Papenfuss]

4)  avidemux2 will split the MPEG2-PS contents of the .nuv files into
component .m2v video and .mp2 audio, using the cutlist to clip out
commercials (using Xvfb to hide the gui from you)
	This step here needs to be avoided... this is where the sync 
issues are caused.

 nuvexport
1)  Use nuvexport's mpeg2 -> mpeg2 cut option to export and
commercial-cut your shows from Mythtv into standalone .mpg files.
(which is using the same avidemux index, split/cut, lvemux re-combine
process as above, all with Xvfb to hide the gui)
	Again, if avidemux2 is used directly on the mpeg2 .nuv files, 
glitches in the stream that cause a change in A/V offset will break sync. 
Avidemux does not handle changing sync... only a static offset from 
beginning to end (which 95% of ivtv recordings have so it works most of 
the time)

Video Quality
Once you get one of these processes working, you still may not be
satisfied with the results.  For example, I don't have my PVR-350 TV-out
working yet, so I'm using an nVidia GeForce 2mx S-video output to my TV
for now.  I'm reasonably happy with the video quality given that my
analog cable input is pretty bad to start with.
	If recorded at a DVD-friendly resolution with enough bitrate, the 
quality should be OK.  I've found in general you need a fair bit more 
bitrate than a commercial DVD since the noise in the signal does not 
compress well.

	My viewpoint is that there are a few underlying issues that need 
to be solved:

1. Correct lossless MPEG2->MPEG2 cutting.  This one has not been 
successfully done yet with any tools that I have found (mythtv or 
otherwise).  Tools like GOPchop are close, but they're a little rough 
around the cutpoints.  The potentially-changing A/V offset makes demuxing 
and remuxing impossible (at least without adding padding frames or 
something to fix sync variations).  The elementary streams have *no* sync 
information as I understand it.  This would provide space savings on 
archived mythtv recordings by removing the commercials without taking the 
time or the quality hit of transcoding.

1a. MPEG2->MPEG2 transcoding.  Not completely without merit.  The 
hardware scaling in the PVR-[23]50 cards makes for lousy recordings below 
480x480, but burning up 704x480 resolution for a broadcast tv signal is 
wasteful of the space.  My personal archival process involves recording at 
something fairly high (640x480) with a high bitrate, and then two-pass 
transcoding (with some denoising) to 352x480.  That final image is *much* 
better than recording at 352x480 directly on the PVR-250, and is quite 
adequate for archiving broadcast-quality to DVD.  I get about 4 hours of 
video on a DVD at VHS-SP quality.  If I were to cut it down to <4 hours, 
it'd be even better than VHS-SP.

2. DVD authoring.  *ONLY* after #1 (or #1a) are solved should anyone even 
think of messing with a fancy DVD authoring GUI.  It's rather complicated 
to do well, and especially complicated to have menus with buttons, 
graphics, etc.  That's a completely separate animal from having correct, 
cut MPEG2 files to begin with.

It's polite (and quicker, and common sense) to search the list archives
for previous topics that may answer your own question. In this case
there have been many threads about forums in the past which would have
answered the OP's question more than adequately.

Unfortunately probably a third to half of the traffic on this list is

There's mailing list archives both at mythtv.org and

Here's what's happening. It'll tune to a transport that you enter and
look for the network information table. That table contains the
frequencies and other data. Once it has that, it will tune each
frequency it found out about and get channel information.

In Australia, none of the stations include information about the other
stations. You'll have to enter all 5 manually.

As well as that, SBS seems to include all of their frequencies, which is
your list above. Myth will tune each one in turn, though only one will
work in your area. Yes it does time out eventually. Be patient.

You can always enter the multiplex information manually (through
advanced in the channel editor), then do a scan of existing transports.
Then it won't look for network information but just use the frequency
data you entered.

Nope!

You could do it in 0.16 I think if you used the video PID for a
different channel on the same multiplex. But not in 0.17, which works
out pids for itself. It specifically ignores non-television channels.

I have had some success with migrating old DVB channel setup to new table 
structures. These were the steps i used - maybe it helps
some too. 
It is paint to do it, but it can be done. I dont know if this has some bad 
effects on system (Jesper?)

- this is done mostly in mysql, i have used Toad for MySQL from www.quest.com 
from windows machine to make things easier for me.


0. In contract to other reports my install of 0.17 with atrpms packages did not 
brop old dvb_* tables - but is is good to have their
backup:
create table dvb_channel_bck as select * from dvb_channel;
create table dvb_pids_bck as select * from dvb_pids;

1. look at table videosource to see what id have a video source that is 
connected to DVB device. DVB channel scanner will create
chanid-s with this SOURCEID*1000. 

2. Check that you existing  CHANNEL table does not have chanid in this 
SOURCEID*1000 span:
select * from channel where chanid between SOURCEID*1000 and 
(SOURCEID+1)*1000;
-- replace SOURCEID with mumber from your setup.
There shouldn't be any records. If there are - which is bad, you could try to 
define new videosource (mythtvsetup will give it first
next ID)

3. Next you must populate dvt_multiplex table. I have done it with channel 
scan, but i belive it could be also done by selecting
distinct frequencies from dvb_channel - the only information missing in 
old-style tables is SERVICEVERSION - and i dnot know what is
this and if this could be left null or 0.
After you have run scan, new channels will be create too - you can leave them 
as they are, or delete them later on.

4. Now the "clever" part, run following query:

select concat("update channel set sourceid=", dtv_multiplex.sourceid, 
",mplexid=", dtv_multiplex.mplexid,
",serviceid=",dvb_channel.serviceid," where chanid=",channel.chanid)
from channel, dvb_channel, dtv_multiplex 
where channel.chanid = dvb_channel.chanid 
and channel.serviceid is null 
and dtv_multiplex.sourceid=SOURCEID and dvb_channel.satid=SATID
and (dtv_multiplex.transportid=dvb_channel.transportid OR 
( dtv_multiplex.frequency=dvb_channel.frequency
AND dtv_multiplex.polarity=dvb_channel.polarity  
)
  ) 
order by channel.channum;

-- replace SOURCEID with SOURCEID of DVB input connection, and SATID with id 
from satelite if you receive more that one satelite
position. 
-If you receive more than one sat (diseq switch), i think you need to create 
separate videosource and input connection for each
diseq port.
-it will give you a bunch update sql statements which update apropriate fields 
(most important SERVICEID) in CHANNEL table.
-if it return less then number of channels you want to migrate, you could try 
changing
"dtv_multiplex.frequency=dvb_channel.frequency" to 
"(SUBSTRING(dtv_multiplex.frequency,1,5)=substring(dvb_channel.frequency,1,5)" 
or
even 
"(SUBSTRING(dtv_multiplex.frequency,1,4)=substring(dvb_channel.frequency,1,4)" 
- this reduces precision of matching frequencies
from old tables to new table to 5 and 4 first digits.

5. You can now delete newly created channels:
delete from channel where chanid between SOURCEID*1000 and 
(SOURCEID+1)*1000;
, or keep than on some high channum:
update channel set channum=chanid+2 where chanid between 
SOURCEID*1000 and (SOURCEID+1)*1000;


and yes - as Jasper said: DON'T FORGET TO BACKUP YOUR DB BEFORE MESSING WITH 
THIS.

You can blame our Australian broadcasters for some of the difficulties.
Specifically:

1. The network information table on each multiplex does not reference
   the other stations' multiplexes, so you have to enter details for all
   5 manually.

2. No program guide data is transmitted.

In the future (if not now) Myth will be able to collect the whole
program guide off the air and you won't need a grabber. Except in
Australia, where the data just isn't broadcast.

Works fine here. Compilation problem?

It doesn't? CVS prior to 0.17 would drop those tables, but that was
disabled before the release. See for yourself at

http://cvs.mythtv.org/cgi-bin/viewcvs.cgi/mythtv/libs/libmythtv/dbcheck.cpp?rev=1.85&view=markup

There's no code to delete records from those tables.

[mythtv-users] Problem with sound cards after 0.17 upgrade

[Phill Edwards]

I upgraded to 0.17 and it all went very well. However, after 1 or 2
reboots the sound stopped working. I think what happened was that
sound device 0 became sound device 1 and vice versa which meant my
favourite program got no sound :( I've had to go back to my 0.16
backup.

1) Could the upgrade to 0.17 have caused this (it all worked fine
before and thenm the day after the upgrade this problem occured)?

2) How can I "fix" the cards so sound device 0 is always sound device
0 to stop this happening again when I re-try the upgrade?

My modprobe.conf looks like this for sound:

#Sound card#
alias snd-card-0 snd-intel8x0
alias snd-card-1 snd-cmipci
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-intel8x0
install snd-cmipci /sbin/modprobe --ignore-install snd-cmipci &&
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-cmipci { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-cmipci

I have a feeling you use paramaters such as "card_limit" and "index" -
would I add something like this to just after the alias statements:

options snd-intel8x0 index=0
options snd-cmi-pci index=1

Re: [mythtv-users] PVR-350 vs FX-5200 TVOut

[Cory Papenfuss]

I finished the VGA->SCART converter...
It finally worked after re-soldering some resistors (the vga2scart website 
mentions pin 18 as GND where it should be 17, Composite Sync GND) and using 
you working modeline for 720x576. Despite the promised improvement I found 
the image quality to be inferior to S-Video.

	Keep in mind that it is always *possible* to get a better signal 
with RGB than with S-video.  It's also possible to get poorer quality if 
not careful more things are in your control to get right or screw up.

All of a sudden the block artifacts in the MPEG stream become very clear (and 
disturbing at times),
	That's because you have a very high bandwidth now... you can see 
more flaws in the upstream part of the system.  (Not a bad thing IMO).

because there seems to be a total lack of correct 
scaling or smooth sampling/filtering of pixels. I see serrated edges all over 
the show and what I like to call 'missing lines', the image seems to be 
vertically compressed vertically and lines are left out to compensate for 
that. Diagonal lines in the video show this clearly. This is what I mean:

\\
\\
--  instead of:  \
  \   \
   \   \
	That sounds like something is horribly broken especially since 
you made a sync combiner for that, it sounds like the TV isn't triggering 
on all the lines.  If you fix that, things should "lock up"

I assume that the Xv overlay should take care of scaling and smoothing, 
right?
	That's the point of the the direct connection... so you don't have 
to scale.  If you record at 720x576, WYSIWYG... no scaling necessary.  The 
only "smoothing" that should be done is what's necessary to prevent 
aliasing in the case of resizing the image.

Another thing is that even now, the TV doesn't display an interlaced image as 
smooth and fluid as the TV-out image w/ bob deinterlacing enabled. Seems that
	That's a tough one to argue and difficult to quantify.  Keep in 
mind that The image *is* interlaced with s-vid.

I am going to stick with S-video output from the TV-out along with bobdeint 
since that gives the best image by far. Sigh, wasted too much time on that 
converter.

	I wouldn't give up on it quite so soon.  It sounds like something 
is broken a bit with it.

	Just as an aside, one thing I've noticed with my converter is that 
since the whole system's bandwidth is extremely high, it's easy to see 
flaws that were otherwise filtered out.  MPEG artifacts, "abrasive" 
motion, etc are all just illustrating how crappy SDTV is.  Normally, other 
limits in the system mask these deficiencies.  Whatever one choses more 
appealing to them is a personal choice, but it's entirely possible that a 
higher-quality picture is deemed as "worse" since it might expose 
otherwise hidden flaws in the system.

I only entered 54350 and I do not expect signal on other frequencies.

Here's what's happening. It'll tune to a transport that you enter and
look for the network information table. That table contains the
frequencies and other data. Once it has that, it will tune each
frequency it found out about and get channel information.
In Australia, none of the stations include information about the other
stations. You'll have to enter all 5 manually.
That is what I ended up doing.
As well as that, SBS seems to include all of their frequencies, which is
your list above. Myth will tune each one in turn, though only one will
work in your area. Yes it does time out eventually. Be patient.
I don't know about that. I left it alone for one hour and it stayed put.
You can always enter the multiplex information manually (through
advanced in the channel editor), then do a scan of existing transports.
Then it won't look for network information but just use the frequency
data you entered.
Correct. I then had to fiddle a bit with the channels to get it right.
Actually, I later discovered that some channels were added unexplainably
again, and this caused all programs to be recorded twice (I have two DVB
cards so it could do that). I had to use MySQL to remove them.
To tell the full story, it was even worse (you still with me?). The 5
analog channels (yes, I have one such card too) had the same xmltvid
as the corresponding DVB ones (which is just right, they do xmit
identical material). The recording and the 'upcoming' showed each
program three times. The machine was brought to its knees doing the
tree recordings concurrently. I fixed the xmltvids.
No really, I am not making this up.

I sent the guy that is working on the commercial detection a video
clip so he could code in aspect changes, unfortunatly this will only
work on certain channels and for certain shows.

To answer the original question though, no commercial detection in the
UK DVB broadcasts doesnt seem to be very great. Back when I was using
a PVR250 the commercial detection seemed quite accurate.

I dont see any easy way for it to detect commercials in the UK, one
possibility is the stripe marker which gets shown up the top right of
the screen just before a commercial is about to start.

[mythtv-users] slow playback of live tv on pundit-r tv out

[Ryszard]

last night, i flicked the switch in myth tv that sends live-tv from
the 350 to the tv out on the pundit-r i'm running.

while the audio was fine, the video suffered lots of frameloss, such
that it looked as tho' it was running in slow-mo.

i was wondering if any other pundit-r owners had this problem.

i'm running myth.16 the 3.12 (patched) ati driver under kde.  i have
no problem with divx or xvid playback coming from the tvout of the
pundit-r, live tv seems screwy tho'

[mythtv-users] XV makes things smurf blue. How to edit XV hue?

[emory]

Hi - 

   I just figured out how to enable XV on my Pundit-R via the ATI
fglrx 3.12 driver and via the mythfrontend (0.17) settings.

   the problem is that now the picture looks weirdly inverted, making
people look blue and smurf-like.

I traced down the problem to the XV_HUE parameter, which looks
like this in xvinfo:

 "XV_HUE" (range -1000 to 1000)
  client gettable attribute (current value is -1000)

-1000 seems very low, since the default is 0.  The problem is that I
don't know how to set the XV_HUE value in Myth or in general.

   After setting up XV in myth, if I watch video in mplayer, the blue
tint is there as well.  But if I run mplayer with:

# mplayer test.mpg -hue 0

  the colors turn out correctly.  And if I watch successive videos in
mplayer without using myth, I don't need to use the -hue flag to get
the right colors.

This makes sense, because xvinfo now shows an XV_HUE value of 0.

  HOWEVER, when I run mythfrontend again, the colors go back to smurf
blue!  The XV_HUE value now goes back to -1000.

  Does anyone know how to set the XV_HUE value to 0 by default in
Myth, or in linux in general?

thanks,

Emory

I don't know of any PCMCIA tuner/capture cards.  The only TV tuners are 
typically PCI or USB.  USB tuners are currently not supported in Myth, 
though hopefully they will be someday soon.

As for firewire, if you live in the US your cable company is required to 
provide you with a firewire-enabled set-top box if you request it.  Be 
aware, though, that you may not be able to receive all channels over 
firewire.

Also, there are a number of firewire tuner devices (like Dazzle), but 
IIRC they output DV, not MPEG, so some work would need to be done to 
support them.

The LML33 is a hardware MJPEG capture card, right?  Depsite doing some 
encoding in hardware, they take a surprising amount of processing from 
the host computer, especially if your capture parameters are not 
optimal.  The CPU requirements for capturing with an Air2PC card, OTOH, 
are practically zero, since the stream is already encoded as MPEG2.  
However, if you receive any HD channels you will not be able to play 
them back on that machine without hardware assistance (like an MPEG2 
decoder, or at least a video card that does XvMC).

Re: [mythtv-users] pundit-r temperatures

I said:

actually, i figured it out.  I made sure that in the xorg.conf file, I
had "no_dri" and "no_accel" set to "no" and then I checked the XV
checkbox in the mythfrontend TV playback settings.

the reason why i wasn't getting a live TV picture before is that I was
getting errors like "X error: Bad Alloc", but I solved those by
placing the line

Option "XaaNoOffscreenPixmaps"

in the fglrx "Device" section of my /etc/xorg.conf file.

Now, my CPU usage is around 20%, which is much better.  The only
problem now that my video is tinted blue.  I started a separate thread
about that, so check that out if you are interested.

Re-reading it, that question was a little convuluted. Let me ask another way.

Is there any way to force a local ringbuffer on a frontend? For
example, watching LiveTV on an HD source fed off the backend, watching
on a frontend. Pause for a bit, then try to FF/REW. You'll see 100M
ethernet (between frontend/backend) saturate as you creep along.
Anything above 5x is pretty much pointless.  Has me thinking about
gigabit between front and back.

However, if I could force the backend to ringbuffer on, say, an NFS
share off the frontend, then the frontend could use local disk to
FF/REW which would be a lot faster.

Thoughts?

RE: [mythtv-users] xbox Mythtv & twinhan or Haupage remote?

[Greg Nicholson]

Thanks!  That was what I am (hopefully) looking for, as I've only been (to
date) able to map about 3 additional buttons not on the Xbox remote.

I've been using Codes from 0522, which seemed to work very well, but
unfortunately had a very limited number.  As you are probably aware, the
Xbox LIRC module is very picky about what it passes on.

I'll give 0059 a shot and hopefully be able to push a lot more codes into
the system (although with .17 I don't seem to be missing the lack of buttons
as much... The onscreen displays and menus actually seem to work in the TV
mode now).

I'm not worried about programming the codes into the remote, that's the easy
part.  Getting IRrecord to do it's thing properly with the Xbox HW is the
fun part, imho.

Thanks,

Greg Nicholson

Subject: RE: [mythtv-users] xbox Mythtv & twinhan or Haupage remote?

Greg,

I'm copying the MythTV users list, just for the
benefit of anybody else who might be following this
discussion.

First of all, I'm not an expert on remote controls or
IR, but I have managed to gain a lot of information
from studying the list (and a person named Harry O.,
who provided most of this information).

For every type of signal encoding, there is a maximum
set of valid combinations that can be done, this will
vary from protocol to protocol.  Not all receivers
have to accept the entire signal set, but many seem
to.

Unfortunately, I don't have any documentation specific
to the XBox, as I'm not using it as a frontend
anymore, but for the general idea of how to program
the All-In-One URC-6131 remote, look at my website,
the page titled, "Using an One For All URC-6131 Remote
with a Hauppauge IR Receiver" (URL:
http://www.vulturesnest.net/mythtvremote.html).  At
that page is a set of instructions for mapping
extended button codes to the buttons that aren't
necessarily mapped by default in RC-5 mode (the
protocol that the Hauppauge receiver uses).  Using
this procedure, I have 48 buttons, all of which are
recognizable with lirc (verified using irw) as unique
buttons, working with MythTV and Xine, on my XBox.

It is a very similar procedure for the XBox.  Get a
universal remote control that supports the XBox
protocol (which is a DVD player of some sort, maybe
Panasonic?), that allows for the buttons to be
reprogrammed (much like the URC-6131).  From there,
once you determine the unprogrammed buttons, you can
look through the extended codes, find ones that you
aren't using on other buttons, and map them to the
unmapped buttons.

A listing of the extended codes for the XBox remote
(DVD player, type 0059) control can be found here:
http://www.hifi-remote.com/cgi-bin2/ueic.cgi?DVD_0059

Not all of those buttons are used by the XBox remote,
for instance, Antenna and Clear.  You can map those
codes to buttons on a remote, and the XBox receiver
will accept them and pass them on to lirc.

Here's an example of the unprogrammed buttons in DVD
0059 mode on my URC-6131 remote control, the extended
button codes I assigned to them, and the lirc codes
(which may not work for you, I can't say for sure)
that detect them:

I just have to say that this is a great idea.

Having full video DVD burning capacity in Myth would be nice, and I
hope it gets incorporated someday. But as Cory pointed out, there are
still hurdles to be overcome.

In the meantime, I completely agree with Brad. A simple, data DVD
burning feature should be relatively easy to add, and would be very
nice.

The transcoder uses the same internal software encoder

so whatever it supports should be supported by the
transcoder.  Honestly I don't know which it is though.

I have the aspect ratio change code working fairly well but have been

recently so I haven't messed with the aspect ratio detection code in
a week or so.  I have it detecting both aspect ratio changes in the

[mythtv-users] ivtv/tuner Problem

[Ryan W. Maple]

I recently decided to check out MythTV again (using mdz's sid packages)
and bought myself a PVR-250 to play with.  Everything is working great
except recording.

I schedule a recording and it records, but it records the wrong channel.
For example I if tell it to record channel 29 it records channel 3 (the
default channel) or, if I was watching LiveTV previously, it records
whatever channel I left the tuner on.

I can change channels just fine in LiveTV so it looks to me like the
problem is somewhere in the recording logic.  Is anybody else having this
problem, or can somebody point me to someplace in the source I can begin
debugging this?

Thanks,
Ryan

Re: [mythtv-users] Sound Problems with Sound Blaster Audigy 2 ZS

[Yan-Fa Li]

Ralph,
Use the F3/F4 keys to isolate the visual controls on alsamixer.
Start alsamixer, then start by hitting F3.  This puts you in playback 
mode.  Mute "Line".  Next hit F4.  This puts you in record mode.  Then
make sure your "Captur" is set for "Line".  Next go to the capture
Slider and set the volume for how much to capture.  This is not tested 
on an audigy, I removed my audigy last week since I needed SPDIF 
optical, but the principles are the same.

Hope this helps,

It seems that I can't repeat the same spontaneous segfault under

Also mythtv log says a lot of these

I tried it out early on, and I would consistently get

That's what I do. In KnoppMyth there is a script that
makes "pretty" named symbolic links to the nuv files
and sticks them into the /myth/pretty directory. I
connect to my MythTV backend via Samba, and copy these
.mpg files to my PC. I then use TMPGEnc DVD Author,
which does a great job of letting you visually edit
out commercials, set up your own menu templates, and
build/burn a disc. Plus it's pretty cheap at $68 for
the basic version.

I've never done it on the Mac, but re-encoding to DV
with Streamclip just to let you use iDVD seems like
too many transcoding steps and loss of quality. There
is a program called Sizzle that will supposedly make a
basic disc out of your MPEG2 files.

[mythtv-users] Dynamic priorities based on available recordings number

[Henrik Nielsen]

Hi
My question or idea is regarding the scheduler and recording priorities, 
and is a result of my usage pattern with mythtv.

Is there a way to let mythtv adjust a recording schedules priority, 
depending on how many episodes are recorded and available to play?

In Denmark, as in propably the rest of the world, all the good stuff are 
broadcasted at pretty much the same time, and as a "single-tuner" 
person, I use the  episode limit in order to spread the recordings 
around the different shows, but this still requires me to record 10-15 
(my limit) episodes from a series, before it will begin to record from 
the series that accidently conflicted with the first one.

The way it could work (I'm not an experienced myth developer, but I 
think this could work):

1) The user (this being me, you, them, anybody) schedules a recording 
with a priority and episode limit, just like normal.
2) The user also checks a box with "adjust priority with available 
episodes", or something shorter, and sets a minimum priority for this 
recording schedule.
3) The scheduler adjust the priority before scheduling the recordings in 
the following way:

   Example:
   Record at most 10 episodes of a show
   Starting priority is 10.
   Minimum priority is -10.
   4 shows available.
   
   This gives the recording an actual priority of:
   
   Priority span: 10 - (-10) = 20
   Priority step pr. show: 20 / 10 = 2
   Recorded shows "penalty": 2 * 4 = 8
   Actual priority: 10 - 8 = 2
   
I am not sure this is doable in mythtv, or if it is already available 
through a script, but my googling found nothing about this being mentioned.

An option could also be to set the minimum priority to a low value 
(-99), and let the episode limit be a soft limit, used only to calculate 
the actual priority. Having a large storage, someone might want to keep 
recording episodes, as long as it does not conflict with other shows.

Please let me know if anyone has thought of something like this. It 
would make mythtv even better for the single-tuner people with few reruns :)

Kind regards,
Henrik

Re: [mythtv-users] Firewire success stories?

[David Madsen]

If you haven't already, it may be worth a call to tech support to
request that it be enabled.  I had to do this when I first started
using the firewire port on my box.  The default version of the
firmware Cox had rolled out did not have the ports enabled, but after
being persistent they did send down a new version that got them
working.

I don't really know that case, but the VFD looks like the one in my
D.Vine5 case (with a cable going out and connecting to the
parallelport ?) In such case, you don't have to worry about it not
lighting up, mine lit up as soon as I had started LCDd, setting it up
to use Driver=HD44780 and Device=/dev/lp0

[mythtv-users] FF/RW faster than before?

[M S]

Hi,

   It seems to me that the FF and RW functions happen much faster than
before.  I used to see that 5x would almost be 5 seconds for every 1
second, 10x - 10 seconds for every 1 seconds and so on.  However...
now it's much faster... when using 5x now it's almost like using 20x
previously, both in rewind and fast foward.  This makes it very hard
to manually ff through commercials and start at the end of those
commercials again, even with the smart feature on that relates
reaction time of actually playing at 1x to when you saw where you
wanted to play.  Is this the case?  Is there a setting that has
changed or that I can change or is this a code change?

Thanks!

I upgraded my driver from 1.5 to 1.6 and it didn't seem to help anything.
I looked through hdtvrecorder.{cpp,h} again to see what'd changed, and 
one thing jumped out at me - the buffer size. In 0.16, the packet buffer

to 128 packets = 23.5KB, which is only enough for a little under 10ms at 
the same data rate. I recompiled libmythtv with the former packet size, 
and recording is much better.

Does anyone know why this change was made? My best hand-waving 
explanation is that the 10ms timer tick on 2.4.x isn't good enough to 
keep a (10-epsilon) ms buffer full, but the 1ms timer tick on 2.6 is. I 
guess I should try upgrading my system to 2.6.x again...

[mythtv-users] Recordings from 0.17 require more CPU?

[stefan hillerts]

Halo Mark,


I'am sorry my English is very bad.


I think my PVR make the same problems after update from
mythtv-0.16.2005 to mythtv-0.17. The System is a VIA EPIA M1000B
with Hauppauge PVR250. I use the hardware MPEG decoder from the EPIA-MB.

When I watching Live_TV after update the cpuload grow up. Under “top”
the sy-load ~13% and the us-load ~12%. The process [ivtv-enc] us much
more cpu-time. After 4 days (much time!) and the background that nxtvepg
(I use it to get the program guide) get ~42% of sy-load I find a little
setting: 

  * run “mythsetup”

  * press 2x ENTER (No, delete ..)

  * press ENTER for 1. GLOBAL_SETTINGS

  * press 2x NEXT, you see at top “TVformat”

  * jump to VBIformat and set it to “None”


Thats the goal. When I watching Live_TV after changing the cpuload is
nice. Under “top” the sy-load <10% and the us-load <5%. On only
recording the hole systemload is <2%.

Pleas post if this little setting is helpful for you too.

Could be.  Most of us are using a 2.6 kernel, so that would explain why we
are not seeing the problem.

It may take me until this weekend, but I will try and verify that a larger
read size does not cause any problems on my system.  If it looks good I will
submit a patch to increase that value.

[mythtv-users] How long should it take to transcode a DVD to xvid?

[Phil Bridges]

I tried my first DVD rip last night.  After a couple of minutes of 
making sure I had mtd running, I put in the DVD, and it ripped to my 
hard drive fine (in less than 15 minutes).  I chose "Good" quality, with 
subtitiles and AC3 audio.  When it started off, Myth estimated about 4 
hours to encode.  Over time, that increased to 12 or so hours.  I went 
to bed, and when I woke the display said that mtd had stopped running. 
Argh.

I sshed to my MythBox this morning, and tried to transcode via command line:

Originally, the EMT (estimated time of what?) showed a couple of hours. 
 Now, it's at 30 hours and counting, at 3.52 fps.  Surely it shouldn't 
take this long, should it?

I'm running FC2, Myth 0.17, AMD 1600+.  Any tips to speed this up a little?

[mythtv-users] mythbackend wont start

[Shalem Shem-Tov]

Hi.  I'm pretty new to MythTV and need some help here.  I installed Fedora 
C3 and followed Jarod's HOWTO.  I got it to (basically) work once, but then 
I guess I did something and now I can't start mythbackend.  When I try I get 
this error:

Starting up as the master server.
2005-02-17 13:12:39.215 mythbackend version: 0.17.20050130-1 www.mythtv.org
2005-02-17 13:12:39.216 Enabled verbose msgs : important general
QServerSocket: failed to bind or listen to the socket
Failed to bind port: 6543
Any ideas?  In MythTV setup I have the IP address set to 127.0.0.1 (I also 
tried setting my actual IP but got the same error).  If you need any other 
info let me know.

Thanks!

Re: [mythtv-users] Video stutters (every sec or so) on 2.6 kernel

Sorry, I don't have a solution but I will say I see almost the same problem
with 2.6.8 on my Debian box.  I see video stutters when I'm recording and
doing live tv at the same time.  But I can watch an old recording and be
recording something else and it's fine.  (And I can record two shows at the
same time if I don't have anything playing back and that is fine too.)

My machine is probably a bit underpowered as I have two BT878 tuners in it
and it's only an Athlon XP 1600+.  I hadn't considered that it could be a
kernel issue - perhaps I'll back off to a 2.4 kernel and try that or tweak
my config some more.

Just out of curiosity, do you have preempt enabled?  I do.  I'm also using
XvMC with NVidia's 6111 drivers if that makes and difference.

Thanks,
Dale

Is MythBackend already running?  Try a killall mythbackend, and then try 
to restart it.

I have the RPMs compiled with opengl_vsync turned off.  Let me know if you 
want to try them out.

It's complaining that port 6543 is in use.  Do a "netstat -a" and see if 
there are
any listeners using that port already.  If so, kill off the process that 
is using
the port.  If you want to find out what processes are using the port use 
(as root
user):

   "lsof -i :6543"
