Back on page 8 you'll see a couple of posts with the solution. They point you here:I'm currently testing with an HTC Desire S and the streaming, even of live TV, works quite nicely.

I still don't have any luck in remote controlling the HTPC from a phone. To that effect, if someone is using windows 7 server and windows 7 client successfully, please give us a sign of life.
