Comment(by paulh):

 (In [12951]) This adds an option to apply a sync offset when remuxing the
 video and audio
 streams together using mplex.

 For the moment you have to enable it by setting the variable
 'useSyncOffset'
 to 'True' at the top of the mythburn.py script.

 I'm not sure what the best way is to calculate exactly what the offset
 should be
 for all files, I currently use the video and audio start times as reported
 by
 the avcodec library to workout what the sync offset was prior to splitting
 the
 file and use the same offset when remuxing the streams.

 I really need somebody who can see the sync problem to give it a try to
 see if
 I'm on the right track or not. The audio sync difference is just too
 subtle for
 me to see, I guess some people are more sensitive to this than others :-)
