Re:Yes, and MythTV (Score 1)

XBMC includes a python interpreter and allows for extensions via python scripts. One of these extensions is a front end module for mythTV which allows you to schedule and playback recordings from a backend server using network shares. The XBox makes an excellent low-cost frontend if you want multiple MythTV frontends in the house, or if you have a big noisy box you'd rather keep far away from your component rack.
