I am pretty sure this card will work fine for my PC work, however when I look at the included setup cables it looks like the HDTV component cables come out of the s-video output on the card. I don't know about getting component cabling from an s-video output, but don't see how this would give a quality image. http://www.newegg.com/Product/ShowImage.aspx?CurImage=1...
It really depends on what inputs you have available on your HDTV. If you have an available HDMI input (i.e. one not already in use), then you can use the DVI-HDMI setup that MadHacker gives.
Some HDTVs come with a "PC" connection that is usually either DVI or VGA. If your TV has one of these available, you can directly connect it using the secondary DVI connection (and included with the graphics card DVI-VGA adapter, if it's a VGA connection).
If your HDTV only has component inputs available, then you'll have to use the included HDTV (S-Video to Component) cable. You should note, however, that the TV-Out connector on the graphics card is not the standard 4-pin S-Video, but a non-standard 7-Pin S-Video, which (according to Wiki) is capable of carrying YPbPr component video.
