Is this with untouched recordings, or files that have been edited in some 
way, perhaps for commercial deletion?

I've seen lipsync problems with transmitted programs watched directly 
(not using Myth). I've always chalked it up to the probable low quality 
of encoding gear at our local small market station, but they only happen 
occasionally, not in any consistent manner.

So, are you sure this is a playback problem, and not trouble with the 
source? Are you able to play back the files in question outside of Myth 
with no A/V sync problems?
