I managed to get Raspbmc and DVBLink's XBMC addin working so I can use a Raspberry Pi as a Media Center extender. You can watch live and recorded TV and browse the EPG, it seems to work pretty well.
I have also got a a Media Center IR remote working with it but am having problems mapping the buttons but as a cheap way of getting TV around the house the Pi is great
