Video/Audio synching problem in VMS/DVDAS

Ok. I purchased an external "ADS Tech DVDXPRESS" video capture device, so I could hook it up to my VCR and upload a VHS movie to my computer. The movie was automatically saved as MPEG-2, with a separate audio file.

I imported these into Vegas Movie Studio and tweaked the audio and video a bit, to balance out the audio between the left and right speakers, and to improve the quality of the video. In Vegas Movie Studio, both the audio and video are perfectly in synch with eachother - from beginning to end.

After rendering the movie and sending it through to DVD Architect Studio, the overall file was too big to fit on a DVD - so in DVDAS, I adjusted the quality of the video to allow for an appropriate file size, forcing DVDAS to re-render the video before burning it to DVD. This took a while, naturally.

When I play the DVD in my DVD player, the movie begins as it should - the sound and video are perfectly in synch. But by the end of the movie, the audio is several seconds behind the video footage.

How can I rectify this? Is there some setting I missed in DVDAS? What am I doing wrong?

Cheers,
Atheryn.

This is a typical symptom of a re-compressed MPEG.

Ideally, you should capture your source files as DV-AVIs, and then go through the rest of the process as you did.

An alternative is to use an editing program with an MPEG workflow, like Sonic MyDVD or quite possibly the DVD authoring software that came with your capture hardware.

Once you've created your initial DVD files, DVDShrink will do a great job of squeezing it onto one disk.
