I was waiting for your post to see if it worked, but it sounds like it
didn't. Have you tried reconfiguring IP using a cross over cable to connect
the Xbox direct to the MediaCenter? This will take the switch, router, and
cables right out of the equation. If it works then you can probably guess its
the switch, if it doesn't then at least you havn't spent money on a new
switch.
