Distro for a media PC

OK building a media PC is a bit outside what I have done before. So I have this PC, a friend is giving me a TV output card which should take care of that part of it but the next question is software. Which distro should I use? What I want is something that can give me a On screen display, as I all this will have in terms of monitor is a TV set, and a rather crappy one at that. It should also be able to pull the files over the house lan from a SMB or NFS share. Other than that it should be as stripped down as posible. Its an old and slow computer with limited disk space.

I am currently downloading debian, but am open to other ideas. To be honest I would rather something red hat/RPM based, just because I've been doing red hat for years.


Thanks
