Well, GATOS plays nice with Xv - in fact it is based on it..

I looked at marvel.sf.net - am I right in thinking that their chip outputs 
MJPEG directly ? In this case it would be quite different from AIW cards 
which produce uncompressed YUV422.

Do you know whether Marvel cards need to use video RAM for transfer of 
video data ?
