Ok, this is making me nuts now. It should be simple and basic and I can't get it to work.
I ripped the audio and video with DVDdecrypter.

I scanned for errors even though I never do (none found by the way). Moved the clips into Womble. That's where it goes funny.
The video is 23.976 with pulldown flags of 29.97 (as is common).
Womble shows the runtime bloated (almost an hour longer) and of course the audio and video don't sync.

So I used dgpulldown and used custom 23.976 -> 23.976. The output file shows as 23.976 at 23.976.
In Womble the runtime is now correct and it ends at the same place as the audio.
Except when playing the preview, the audio and video are out of sync even though the visually the two parts are right.
Any ideas here?

Edit: I found the problem. The video has to be extracted as Raw not Demuxed. That's interesting.
