Comment(by dl-mythtv at catspoiler.org):
Same problem here with 720p material 0.21-fixes on FC9 with an Athlon64 X2
4000+ on an Abit AN-M2 HD motherboard using the onboard Nvidia graphics.
It appears the the problem occurs when AvFormatDecoder::GetFrame() is
processing a large number of sequential video packets without any
intervening audio packets, and the audio output buffers drain. I don't
know if the problem is that the loop that calls vFormatDecoder::GetFrame()
is taking too long, or if it is being blocked by a shortage of video
buffer space. In the log file excerpt that I will attach, the last "audio
timecode" is processed at 18:52:51.807, the internal audio buffer is empty
by 18:52:52.047, and the sound card buffer is empty by 18:52:52.385. The
next "audio timecode" does not occur until 18:52:52.776.
