 	Doesn't surprise me.  Even a 20 year old VGA card can do twice the 
bandwidth required of SDTV.  Newer ones are more like 20x (350MHz dotclock 
vs 14Mhz for SDTV).   I've done something similar (although I'm 
using an analog S-vid chip for NTSC).  No scaling done, just build the 
proper modeline and see tvout the way it was meant to be.  Crystal-clear, 
readable terminals, high color fidelity, and unparallelled sharpness for 
SDTV.  Of course it's 30Hz interlaced, but that's something to be lived 
with (since SDTV *IS* interlaced)
