OK about to build a New PC.

So the one I'm currently on , just looking to hook up to the living room TV for home movies etc [not that kind ]

With a Virgin + box, is there a way of going from Virgin box > PC > TV all in HD?

Ie would it be hdmi cable from virgin box to pc , then hdmi cable from pc to tv ?

does that make sense !

or I guess maybe hdmi from virgin box to pc , scart from pc to tv hmm

What do you folks think ?
