So this happens only on H.264 videos? What is the source of
those<br>
videos? Are they all recordings, or does it happen on
downloaded<br>
H.264 files as well? Are the affected files interlaced?<br>

<div>H.264 recordings from Comcast seem to play back fine.
It's only archived Blurays (which is why I assumed maybe it
was a bitrate issue). </div>

You did not mention what version of MythTV you are running. With V30
(master) you can try the new AVSYNC2 in the playback advanced
settings. Also run with -v playback and see if it is dropping frames
or waiting for video buffers. Those messages will tell where the
problem is. Waiting for video buffers means a decoding problem,
dropping frames means a rendering problem.<br>
