If they're RGB, probably go for PNG as input. I'm not sure what raw
YUV formats mplayer supports right now, but there should be something
that works.

Dual won't help you one bit. Go for the maximum clock you can get
instead. For max video performance and quality you should probably get
a Matrox G400. That way you can use mga_vid, which will avoid some
unnecessary copying from going through the X server, and updates will
be synced to vertical retrace so you won't see shearing. Also the
filters are said to be much higher quality than on the "gamer" cards,
but I don't know much about that.
