Not sure, since my personal experience is that with finally getting the
component out on the Nvidia card to work, I have the best Myth display I
have ever had, and that is with using composite, s-video, 3 different
VGA transcoders, and finally the component out. I can't see how my
picture could get any better at this point, for me anyway. I'm sure my
setup is far from normal though.

If 576p is a standard HD definition, then you should be able to use
'HD576p' as the the TV Standard in xorg.conf.
