Usually when audio gets out of sync over time it is a problem with sampling rates that differ from your playback rates. But it could be a problem with the timecode you are using as well. Drop frame versus non-drop. I’m really unfamilar with the DAC-100 but does it produce two different capture files- one for audio and another for the DV video? Your problem sounds remarkably like the problems we used to have with the early AVIDs.
For others here was Scott’s original posting:
I read the post about the sync problem and mine might have the same problem, but I will post any way. I am trying to capture from a VHS through a datavideo dac-100. I have done this before with no problems, but I just recently upgraded to from a G5 to an intel mac. Once digitized and in the timeline, the audio plays fine, but as is plays longer, the audio slips more and more out of sync. I did notoce that the audio setting on the timeline was at 48.0 and the same setting for the clip is something like 4753859.0. I tried to capture a little at at time, but the further I got in to the tape, the audio number would get further and further away from 48.0
