I know that plenty of audio synch issues have been reported here, but I can't find my case here. I am taking a 2hr51min DVD (Curb Your Enthusiam Season 1) and encoding to Xvid. The sound loses synch exactly when the first episode ends and the second one begins. The second episode's sound is at least one second ahead. The problem progresses per episode. The DVD source is perfect. I am using GKnot 0.28.7 and Koepi's 1.0.2. I am just muxing the AC3 (but the same problem happened when I converted to MP3). Also, each VOB contains one episode. So the problem is happening as GKnot automatically moves from one VOB to the next. Remember, I am trying to encode this perfectly. I don't want to do any post-encoding synching.
