[MPlayer-users] How to use YUV input

I have an assignment foor a class on Multimedia, in which I have to 
encode/decode RAW video files in YUV 4:2:0 format (352x288,30fps) for 
starters. Then I also have to do some scene description stuff using XMT 
and BIFS, ... But that's not your problem.

Now, as I understood from the manpages, it would be possible for mplayer 
to handle these RAW files using the -rawvideo option. Alas, I think I'm 
using the wrong options or something, because this is what mplayer gives me:

lacke at lennert XMT $ mplayer crew_352x288_30.yuv -rawvideo

Does anyone know what I'm doing wrong ?

Your help is much appreciated,
