some homebrew original xbox apps do work. I have had luck with some of the emulators, and some of the homebrew games(DoomX works, but randomly fails). as for xbmc, i have read that some have gotten it to start, but it wont play video files, and freezes alot. There are other video apps made for the xbox 360, while the best one is a Mplayer port called XMplayer, and runs in xell.
