no, it's a bug (or what) in divx and mpeg4 codecs.
there is a workaround, it's called YUVHACK by me. you must init and query
the codec with RGB16 format, but change the biCompression field to YUY2
(or other YUV format) whan call decompress. It works this way.
I dunno why aren't YUV formats accepted by init/query functions.

your video card is slow for displaying RGB frames, isn't?
