Ok, that's really what I was thinking, but since it was available as part of
some of the mjpegtools packages on the download page, I was hoping someone
might at least give me a clue...and $DEITY knows I need a clue ;-)

actually, the script does provide and option for setting the framerate to
24000:1001, and since no one had replied by the time I was going to bed, I
thought, what the heck, CD's are only about 50c each...

I forced my brain to do some logical thinking, and I figured if the sound is
*behind* the video, then I need a *lower* framerate. So I did the encoding
forcing a framerate of 24000:1001 and *BINGO*  it's dead on.

Thanks very much for your reply!
