I would try to get schorman's laserdisc audio archive and simply use his audio files to sync to your project or capture video and audio separately. Capturing without audio simplifies the whole process of capturing and reduces a bit of overhead that might be causing your system to drop/insert frames. If you get 1 single dropped frame or 1 single inserted frame then might as well start over. I tried to disable all of that resync stuff,etc. in Vdub. The timing options should all be turned off basically. I never have to this day gotten a dropped frame or inserted frame using my ati theater750 btw. I think if you tweak Vdub a bit you won't either.
