Just in case;

Hey Brad, It just occurred to me that folks might not realize that with this 
latest generation of nVidia Cards, a new set of TV formats have been 
implemented as options for the TV Out port on the cards. You may now do stuff 
like;

Option "TVStandard" "HD480i"   or
Option "TVStandard" "HD1080i"  or any of the other HDTV output formats

It is possible that there is some sort of scan converter onboard the card but 
I don't know tis for a fact.  For example, the TVOne box ($250) that I 
mentioned earlier takes a 1600x1200 signal and creates a 1080i (or whatever) 
output format.  The 6 series cards look suspiciously familier in this regard.
