VideoGrabber is an external on Mac and Windows for er... grabbing video and 
audio.  See Video category on Dictionary.

I don't think frames were skipped, the sync is reasonable, it's just that the 
sound runs out before the video does.

We did a lot of tests with a running clock before we started - but it had a 
very quiet tick and we weren't paying attention!   More to the point, this is 
very intermittent - we've seen a handful out of about 2,000 clips.  Mind you, 
we haven't necessary reviewed every clip to the end.
