I don't think your colour issue has anything to do 
with MMX.
All codecs (that have any relevance) only support 
yuv420p in the variants supported by the "free" 
(as in beer) multimedia players, so it makes sense 
for FFmopeg to default to yuv420p if nothing else 
was specified and it makes sense for video drivers 
to only support yuv420p.
Note that even vlc has / had issues with h264 rgb.
