I am experiencing audio synch problems and pitch shifts when I burn a DVD. I am capturing TV shows from a VCR using Pinnacle Moviebox USB - for a 2 hour capture (4 shows) there are zero dropped frames. I have also captured some using Adaptec VideOh PCI.

I am using Pinnacle Studio 8 to edit out the commercials. I have also used Womble - same synch problems. Finally I am using Sonic MyDVD to create a 4 show DVD project, and burn DVD+R on a Sony desktop. The AV synch is fine for the first 10 minutes or so of each show, nut then the pitch shifts on the audio (as if the sample rate changed) and synch is lost. I am automatically creating chapters every 90 seconds to facilitate editing. But I had similar problems using Womble with no chapter points.

Any ideas? Looks like AV synch is a common problem, with many different proposed solutions.
