I like the free and excellent GB-PVR, personally. On our Ultimate Boxes, we don't bother enabling Win Media Center functions - the Hauppage TV cards offer better versions, or the ATI's work better with GB-PVR. (Yeah yeah, I know that's not what it's officially called anymore.)
By the way, I think the next Microsoft OS will be code named NASCAR.
Instead of desktop icons for your applications, you'll see endless commercial logos and you'll have to play CONCENTRATION - trying to flip over 'tiles' until you find your application's Two Matching Icons.
MS is going to say this is more secure.
"Since people can't launch applications, they can't have infected computers nearly as easily. We've finally got a secure OS, and it's called NASCAR."
Of course, just before release, some motley crew will complain to Ballmer and he'll insist, "OK, this was NEVER called NASCAR, and now we're calling this Interface AMC Gremlin. Let's see if those people EVER sue us!"
