Ok I have an Xbox360 and Windows 7 Pro x64. My router is a 3800HGV-B.

What do I need to do to connect the 360 to windows media center? I have tried just about everything I can think of and can get no further than the connecting screen. This includes turning the firewall completely off and going to ethernet

The 360 and computer see each other. If I do a bandwidth test on the computer while the 360 is showing the connecting screen I show that I can do everything but HD video which is fine.

Due to other problems I have replaced both the 360 and router.

I am fairly well versed in computers and networking but this has had me quite confused.
