After some further experimentation I came to the following conclusions…

The VHS that I am capturing from is pretty old and causes alot of screen flash/flicker. ( mostly toward the beginning of the tape.
What I did was break the tape up into segments and recorded each one. The later segments of the tape I had no problem with, and video and audio sync were fine. The first portion of the tape, where most of the screen flash and flicker occured was where my audio and video would get out of sync. After various attempts to record and re-record the first section of this tape I noticed that what I ended up with for video and what I saw as I previewed the capture process differed slightly. Following the capture I noticed that their seemed to be ever so slight jumping in certains sections of the capture as if frames were missing from the video capture.
It is my belief that the capture process is eliminating frames associated with the flash/flicker possibly as part of the compression process.. possibly as part of some sort of filtering process. The audio meantime has no issues and is fed back through my audio card for capture. Hence I end up with video and audio portions that are not the same in length. By clipping pieces of audio in strategic places and then stretching the audio clip to match the length of the video clip I manage to re-sync the A/V to something acceptable for this beginning portion.
The question remains as to what might cause this “clipping” of bad frames in the video. My suspicion is that it is actually associated with the video card or the ATI drivers, but I’m also supposing that there may be some setting in Vegas that allows this “filtering”
