[mythtv-users] No Playback, Live TV OK

[Steven J. Finnegan]

I seem to be having some problems with playback of recorded programs. 
"Live" tv works just fine.

Some time back, after an upgrade maybe three weeks ago, I discovered that 
recorded programs were playing back with very low audio. (Again, live TV 
audio level was fine.) To try to compensate, I went into the various 
profiles and bumped the audio level up to 100 percent. I have been unable 
to play back any recordings made since that time. The screen goes blank, 
and eventually the frontend seems to crash.

Yesterday, I upgraded both IVTV and Myth to the current CVS versions. This 
problem still exists. I believe this is due to some kind of audio problem, 
since it started when I changed the audio level, and playing back the 
captured files on a windows machine shows video, but NO audio at all. Also, 
the preview display works fine -- but of course it doesn't use the audio.

Last night I set the system to record 2 half-hour shows at 16:00 (PVR250 
and PVR350 tuners). Some time later I started playback (well, attempted 
playback) and just left the system alone. This morning, the frontend had 
crashed with the following messages in the messages log...

Oct 31 16:00:03 atlas kernel: saa7115[0]: decoder set size

Oct 31 16:30:02 atlas kernel: ivtv: Not enough free buffers, stream 0
Oct 31 18:10:04 atlas kernel: Out of Memory: Killed process 4575 
(mythfrontend).

Anybody know what is going on?


Some more information -- When starting playback of a recorded show, the 
frontend ends up sucking up all available memory.  Here are the first few 
lines of "top" a few minutes after attempting a playback...
