Do you get similar desync when playing the movies directly from DVD using
MPlayer, or does this only manifest when transcoding that way?

Is the size of the desync consistent within any given rip, or does it vary over
time as you let the movie play?

Do you get the same desync with e.g. ffplay?

Is this on playback, or when encoding?
