Andykard, I think the audio is out of sync, you just don't notice it :) You can check the delay after reauthoring, after all, and find out for yourself :) And you can drag AC3 audio to the right (2 ms increments, I've found). In this case I'd cut 2 frames, creating a +1 ms delay (-63 + 2x32). Then if you want to be exact, drag 1ms to the right in Maestro. In other cases the delay can be a bit larger after cutting, e.g. -82 ms would end up as +14 (-82 + 3x32).
