I believe I have found an explanation, and that -oac copy is the cause.
Using: MEncoder 2:1.0~rc1-0ubuntu9.2 (C) 2000-2006 MPlayer Team

I recently got a newer DVD Player(Samsung 1080P7) and it will not play ANY
avi created with -oac copy as above.  The audio comes out in chirps and
the video in jerks at about 5 second intervals.

The Player has a digital counter.  During play, the counter sequences up
to 5 and then returns to 2.  Next it runs up to 6 and then returns to 2
again.  This pattern repeats 2-6, 2-7, 2-8, 2-9, etc.  Eventually the
counter returns to 3 and the pattern begins with 3-n.

Is it possible that the avi is not interleaved correctly and therefore is
unplayable on CD/DVD media?
