It does? News to me. It's been 2 years since I tried xbmc, and when I last tried it, a fairly decent machine struggled with HD playback while Mediaportal (and MPC and others that used avivo and purevideo). I did a quick search before posting to make sure I wasn't mistaken and saw this:
> Note! Developers wanted! XBMC does not yet support any listed methods of hardware accelerated video decoding.

So I didn't do more digging...but that page hasn't been updated so 2009, so my bad.
I highly recommend MediaPortal http://www.team-mediaportal.com/
The setup is significant, but once you have it going, it's great. You can use hardware accelerated h264 decoding (whereas Boxee, XBMC and many others are software only). The plugins for it have great, poweful support for automatically matching Movies and TV shows based on regexps and online lookups of the filenames.
