Dual head graphics card for HDTV

[arunm]

Im looking for a graphics card that can run two LCD tvs at full screen with no stretching (720p). I'm not fussed about the hardware interface, but I would prefer digital. Does such a thing exist? I've seen dual head DVI cards that support HDTV, but i'm not sure about how that will handle the aspect ratio.
Any suggestions would be appreciated.

The 2600 XT radeon cards seem to be pretty good for this, not so great for games but built in HDMI support and a lot of hardware acceleration (MPEG 4 DivX plus more). That's what I've been looking at for my new HTPC set up, also quite a few available as passive cooled so no noise (from the card at least will probably bump your case temps up a bit so maybe a bit more work for the case fans).
