media center with my xbox 360

[Guest blairo32]

So i just installed Windows Vista Home Premium (Build 6000), i've never had

my xbox360 connected to my computer but ive been trying to do it with vista

and my xbox360 can't be found on my Vista computer, but i cant still play on

xbox live. Now im not sure if i have to allow something through my linksys

WRT54G router, or just something with my firewall. Ive been trying different

things from every site to fix this but nothing is working. On my xbox360 when

i do a media test PC selected fails everytime so any help would be

appreciated.
