that requires a little more work as normal VGA is 5 seperate signals, but it 
is possible, as its what the VGA->HDTV converters basically do.

I too am interested in knowing if anyone has had luck with the HDTV output 
capable cards and how the work? Its looking like my TV doesn't like 1080i 
from a regular DVI output on video cards and using a HDTV chip with 1080i via 
component cables may be the way I need to go.
