hrm.  doing mplayer -v on the sample avi gives the the following:

======= VIDEO Format ======
  biSize 40
  biWidth 352
  biHeight 160
  biPlanes 1
  biBitCount 24
  biCompression 808802372='DX50'
  biSizeImage 168960
===========================

The closest I get is this:

======= VIDEO Format ======
  biSize 40
  biWidth 352
  biHeight 240
  biPlanes 1
  biBitCount 24
  biCompression 808802372='DX50'
  biSizeImage 253440
===========================

With this command:

mencoder matrix4.mov -oac mp3lame -lameopts cbr:preset=128 -ovc lavc
-lavcopts vcodec=mpeg4:vbitrate=50:vstrict=1 -ofps 20 -ffourcc DX50 -vop
scale=352x288 -o movie.avi

the biSizeImage needs to come down some more, but I'm already down to a
50 vbitrate.  Is this relevant?

I do get sound - just no video.  I tried 32 anyway just to see, and got
the same result - seems like audio's not the problem...
