XBMC was fantastic. I soft modded my Xbox so you would boot into XBMC and the eject button no longer reset the system so you could swap your Xvid, WMV, mpg, ogg, jpg etc files on dvds to your hearts content. it did a good job of scaling the picture for different regions and everything :)
That was my primary use of the Xbox since I couldn't afford that many games.
