In some cases, I've heard of 1080p over component (apparently the  
interface does have enough bandwidth), but I believe that most TVs max  
out at 1080i over it.

The resolutions being quoted sound like they're for VGA and not DVI -  
although anything is possible.

If you have a DVI port on your video card, then just use a DVI to HDMI  
cable for the video.  Most TVs, I would imagine (I know mine does)  
have a separate set of analog inputs to accept audio for either VGA,  
DVI or HDMI connectoins.
