I saw this somewhere and checked it out. It looks like something I would want to use.

However, I don't know if I want to be running anything Windows at my house. Does anyone know if there is something like this out there that I could use (mainly the TV Tivo-like capabilities and MP3 player)?
It would be awesome if Apple released a Mac OS X version of something ilke this. But I don't think we'll be seeing anything like that in the near future. If Tivo could stream MP3s off a MP3 server, that would be good (however, I like the fact that the Media Center doesn't charge for TV guide service).
