Yeah, I think your right there... or maybe the sharer has added the glitch themselves? I don't blame them really, I wouldn't want anyone selling my shared stuff either.
The only reason I like to burn my video files is so that I can watch them on a nice big TV, instead of having to crowd round my tiny monitor and watch them.
Anyhow, let us know how you get on with SUPER General T... i'm interested to know if this would work on these files.

I have the most simplest, and quickest solution
Burn the episodes as a data disc.... it takes about 5 mins to burn 5 episodes using nero! Or just use your back it up to DVD option on your PC... ensure your downloaded video file is encoded with DivX/Xvid, it will be if its the same one as I got.
Get a DVD player that plays DivX -(if you don't already have one)... and hey presto, plays exactly the same as it would on your PC with lip synch intact
Although I might add that I'm only gonna use this for out of synch video files... just in case in the future you can't get DVD players with this feature 'cos there'll probably be another newer feature then to replace DivX!
