Hi, I have a problem with my xbox 360 as a media centre extender and was wondering if anyone can help? I have changed my xbox 360 mac address to that of my pc to enable the xbox 360 to go online, however it won't talk to my vista home premium pc. I have a virgin media dsl modem connected to a netgear powerline hdx101 which is connected over my electrical mains to my pc via another hdx101. I have a 3rd hdx101 downstairs which my xbox 360 is plugged into. All hdx101 have the latest firmware and they work fine as they have all been swapped around. The hiccup occurs when I try to connect my pc to the xbox 360 as a media extender. I enter in the 8 digit code correctly, but the vista pc cannot detect the xbox 360 for some unknown reason. I am completely at a loss and don't know who to contact, as my internet is working fine, the hd powerlines are working fine as the router can talk to my pc and the xbox 360 itself can connect to the xbox live servers and finds itself an ip address after going through the pc's mac address. Do I need another router? How would I connect it? Is there another way to get it to work? I really hope someone can help as I am at a complete loss. Thanks.
