> it. And I would just stick to all fourcc (4bytes) for audio aswell. I


and may i suggest to do mpeg audio/video more consistant?

mpegX      video "MXV",0 (M1V,M2V,M4V)
mp3     "MP3",0
AC3     "AC3",0
H26X    "H26X"

and a generic suggestion that the file extension should be used as
fourcc if theres a well known filename extension for the elementary
and generic suggestion 2 if theres a well known avi fourcc then that
should be used
