I want to run the ethernet cable from the 360 to my modem router that's connected to my PC so I can use the program ORB to stream all my music and videos. If possible, I want to configure it so that my 360 doesn't connect to XBox Live when I have it plugged into the modem as it usually does first chance it gets. I know you can go to the auto-sign in menu on the 360 and turn of auto signing in of XBox Live and Windows Messenger, but will that stop it completely? Should I maybe go to my network settings and just set the IP and DNS servers to something random that would never allow it to connect? I can't plug it into the PC and avoid the modem as the PC doesn't quite reach. Any suggestions?
