    I have the same motherboard and the tv encoder dot clock (used by 
component out) has a 400MHz max dot clock.  I don't know what the DVI 
ports max clock is though.  I think the point is moot though, as my 720p 
is only 74MHz, and 1080i should be about the same.

    I found the quality to be much better using the DVI port from that 
motherboard to my Panasonic LCD Projection (720p) television.  However 
it only has 1 digital input on the back, which goes to the cable box for 
now.    What modelines are you using for your 1080 and 720p?  My 720p 
over DVI is razor-sharp.  The NVIDIA drivers have built-in modelines for 
standard resolutions too.  I'd try the mode "1280x720_60" if you haven't 
already.  There's also "1920x1080_60" and "1920x1080_60i".
