I don't know how it can be used for HDTV, but it can output an HD picture for games. You need to attach an HD component lead (Microsoft or Gamester) to a US Xbox (or a modded PAL one). Also the game itself must be capable of outputting a 720p or 1080i signal (which currently only a few imported titles can do).
Cheers,
Ian.
