Ok, so my computer recognizes the xbox but on the xbox, it says pc not listed. I've tried opening ports, tinkering with my wireless router all to no avail. It used to read the PC but just doesn't work anymore. I'm also using Windows Media player 11 to share the files. I've tried other sharing programs such as "Zune" and "Orb". I've also tinkered with the "services" on my computer, turned on UPNP, Media sharing etc. HELP!
