Errors and Solutions
tv_grab_uk_rt - Undefined argument in option spec
Edit /usr/bin/tv_grab_uk_rt and remove days and offset args from GetOptions variable list, and replace with:
'offset' => \ my $opt_offset,
'days' => \ my $opt_days,

MythTV and LIRC
Using the Ctrl key in config lines
Contrary to some sources, the required format for the config line is config=Ctrl+X. For example:
begin
prog = mythtv
button = TV
config = Ctrl+2
end
Repairing broken MythTV tables
- Stop MythTV and MySQL
- cd /var/lib/mysql/mythconverg
- myisamchk *.MYI
- Identify broken tables
- myisamchk -r brokenTable.MYI
- Restart MythTV and MySQL
This will often happen if (with an nVidia driver), the nVidia libglx file has been overwritten by an xserver upgrade. To check for this, run glxinfo | grep direct - if the driver is working the direct rendering should be on. If not, check the /var/log/Xorg.0.log for:
(EE) NVIDIA(0): Failed to initialize the GLX module...
In this case, it's possible to reinstall the latest nvidia linux driver, or alternatively, simply (as root):
mv /usr/X11R6/lib/modules/extensions/libglx.so /usr/X11R6/lib/modules/extensions/libglx.so.orig ln -s /usr/X11R6/lib/modules/extensions/libglx.so.<nvidia ver> /usr/X11R6/lib/modules/extensions/libglx.so
BBC HD
Not yet possible to play this in MythTV yet, as far as I'm aware. However, you can save it to a file, and play it back (slowly, on anything but very powerful hardware).
- Grab latest x264, ffmpeg and mplayer from svn, and compile manually.
- Add the following to your channels.conf:
BBC HD1:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:1502:1505:36932
- Tune to the channel, and check you're getting lock with tzap "BBC HD1"
- Grab a portion of the stream with dvbstream -o 8192 > myfile.ts (Note the use of dummy PID 8192 - this tells dvbstream to record the entire transport stream, rather than just selected program streams).
- Playback the stream with mplayer myfile.ts. MPlayer should tell you there are two program streams - an H264 video on pid 1502, and an a52 audio stream on pid 1505. Sample mplayer log snippet below:
Playing myfile.ts. TS file format detected. VIDEO H264(pid=1502) AUDIO A52(pid=1505) NO SUBS (yet)! PROGRAM N. -28604 FPS seems to be: 25.000000
