Would using MP4S present any problems? I know MS used this at one
point in AVI but I'm unclear on whether it referred to a restricted
profile or full MPEG-4 ASP. If it's acceptable it would be one less
difference from AVI.

BTW this document should explicitly mention that DIVX, DIV3, DIV4,
DX50, 3IVX, XVID, etc. are reserved fourcc values and invalid. :)
