Stumbled over this while searching for tweaks:
Media Portal turns your PC in a very advanced Multi MediaCenter / HTPC.
It allows you to listen to your favorite music & radio, watch your video's and DVD's, view, schedule and record live TV and much more. You get Media Portal for free/nothing/nada/noppes and best of all it is opensource. This means anyone can help developing Media Portal or tweak it for their own needs!
Anybody use it?
