Number one son has been playing with an XBOX 360 as a Media Centre extender. He's also been using the latest version of Vista. Lucky fellow.
Anyhoo, turns out that an XBOX makes a very good extender. And it worked with Vista right out of the box. The experience is pretty much as if you were sat at the real computer, picking music, looking at pictures and watching live or recorded TV.
The network lights up like a christmas tree when you use it (although we are using a slow old style yellow wire one for some bits) but the pictures that come out of the other end are pretty darned good.
However, this is not helping my case to get a Media PC downstairs in the living room.....
