It could be there is a jump in the PTS at these points and mythreplex
isn't handling the jump properly but without a sample file I'm just
guessing.

I've said this many times before but the only way these sorts of
problems are going to get fixed is if someone takes the time to provide
a sample file so that I can reproduce it. Ideally a native archive of
the original recording made with MythArchive so I can use the same cut
points etc.

It's at the top of the mythburn.py script.  Just change
useSyncOffset = False
to
useSyncOffset = True

This just fixes one instance of the audio sync problem where playback
starts out of sync and stays the same throughout the file.
