It seems that only M2 clips are out of sync. When they appear in either of the 2 films I shifted them 1 frame. It LOOKS like that fixed all of the problems.
I didn't fully sit through all of M2, only 20 minutes of the beginning and end, which should be the proof enough.
I still want to sit through M3 once more since I'm not as in love with it as I am M2. Not because of sync, only flow of the movie (and possible audio bugs).
I'm TRYING mightily to get it on Pirate Bay, but the audio will not sync in the Xvid. I've tried raw ac3, I've tried resynching 14 ways to friday with VDubMod. I've used the raw mpv & ac3 files I've used rips from temp burned DVDs. I even installed Auto GordianKnot and pointed it at the finished DVD folder to see if automated software could take out user error. It will not sync.
The DVD is beautiful, but an Xvid seems impossible right now. One more idea left...
On the up side, if the Xvid wasn't this bad I would never have seen the subtle out of sync in the M2 clips since I wasn't looking for that.
Edit: Reinstalled Xvid codec and trying one final time. If that fails I think I might torrent the full DVD. It'll be slow, but I really want some feedback before I start burning and sending discs.
