You got your next gen console, your next generation PC playing with beautiful next generation DVD's playing on your high definition TV, you wouldn't connect it up with LAST generation wiring now would you?
We didn't think so, but just in case, the Copper Development Association would be more than happy to show you how. They recommend wiring CAT5 and RG-6 throughout your house in a star configuration around a central distribution device. That way you can wire your internet and television to one place, and distribute it throughout the house easily.
Of course, you'll probably want an installer to do that kind of work, and I'm sure they know someone they can recommend.
