Actually, Leon, since I got this working last night, I've been
successfully recording at 90% (though I haven't tried higher).

Just so you know (and those on the mjpeg list might have already seen
this) I only seem to have two problems left:

1) lavplay and xlav seqfaulting (even with software playback).  gdb otput
   sent to the mjpeg list.

2) I need to have the audio from the VCR (or other composite device) go
   directly into the line-in on the sound card, and route through the RRG.
