If you fancy an interesting project look at MythTV as a combined TV distribution system..
It can combine Freeview, Freesat and other Satellite systems all into one delivery platform as well as including all your videos and music. You can watch via HTPC on your TV or even via a web browser using mythweb.
I first installed it about 4 years ago now and me and the family could never go back.
As it's Linux based it's all free and if you're not a Linux person it's a great way to learn.
