eh.
you should ask mplayer to do that, ie -vop yuy2 or -vop format=yuy2
i'm pretty sure it's faster & better than the SDL version...
and you can optimize it in postproc/rgb2rgb.c:yv12toyuy2()

SDL should be able to access hw directly, at least on linux+X11 it does.
maybe you need mplayer option -dr to activate it...

great!

btw what about the mplayerosx.sf.net project?
i assume they have native rendering driver instead of buggy slow SDL.
