I *assume* that the audio starts in-sync. Honestly, there's no way I can check
that. I can, however, check the audio relative to video position at the end of
the whole thing by re-capturing just the very end of the program, then finding
the same video frame and from that point of time copying audio.

If you can't check it, then I assume there is nothing up front that _needs_
to be synched. If that's the case, just shift everything five frames and
let the beginning be out of synch. If there is no dialogue and no synched
effects, it doesn't matter if you're a couple frames off.

If there is dialogue and synched effects up front, then you certainly can tell
if it starts in synch.
