I've had a similar problem on occasion. Not with your specific software and conversion but with AMV conversions.

One particular episode of a TV series wouldn't convert from VOB to MPEG1 using SUPER converter (pre VDub processing) without the audio becoming unsynched as the episode played. The other 8 episodes on the DVD converted fine but this particular one wouldn't convert properly.

I tried all sorts of approaches including changing the settings in SUPER and converting to various formats using several codecs. Nothing worked.

I finally cut the episode into 4 five minute segments and adjusted the audio track postiion in VDub, for each of the 4 segments. That worked somewhat but took a lot of time as the shift got progressively worse in the original SUPER conversion, as the episode played. When I was done, the audio was still slightly out of synch by the end of each segment.

Recently had a similar audio synch problem with an animated full length movie. Both DVDs were original ones that I had purchased so the source was good. One was animated content and the other wasn't.

What I've ended up doing to resolve this has been to change my approach in capturing the original source. Even if things go smoothly, it takes a long time to rip a DVD, convert the VOB files to MPEG1 to feed into VDub, process with VDub then finally to AMV. Processing from VOB to MPEG1 using SUPER takes about as long as playing the piece, never mind the other stuff and this is if there is no additional fiddling required.

What I do now is to connect my DVD player to my computer via a Hauppauge input/caputure device that I have. Play the content and record it using the MPEG1 VCD recording option in the Hauppauge software.

I can open this file directly with VDub as it is recorded in MPEG1, do my image adjustments, audio adjustment and splitting (5 minute chunks usually) using VDub and then convert to AMV. It takes much less time over all and the results are predictable.

This approach can be used to input direct TV feeds, VCR tapes, digital camera videos, ... . Also, the Hauppauge software seems stable and processor efficient so my computer is usable while the initial capture and MPEG1 recording process is occurring. I expect this approach would work with capture devices in general.

Hope this helps.
