[mythtv-users] mytharchive audio broken

Tue Sep 11 19:12:27 UTC 2007

I've been wrestling with mytharchive ever since I got mythdora installed and 
running. No luck...

I've done a 'yum upgrade \*myth\*' recently so I'm at the 0.20.2-164 level 
of everything. I'm even using the schedulesDirect stuff, so I know it's the 
latest revs.

My Hauppauge PVR-350 saves stuff as 480x480. I can play back the recordings 
fine. I just can't seem to get it to re-encode to DVD SP format...or any 
other DVD format for that matter. When mytharchive completes, the VIDEO_TS 
directory has the expected stuff in it, but the AUDIO_TS directory is 
empty...so the resulting image won't play.

I've got 'always run mythtranscode' checked, and it does seem like it's 
trying to transcode to 480x720. I've tried SP, LP, EP, no transcoding...it 
always comes out with no audio data in the directory.

HELP!!!!

Here's some stuff from the mythburn.log:
