I signed up on Bungie.net just for this problem, DRE on matchmaking and campaign. I called Xbox Support to get this issue resolved only to be asked to spend $119 to get my console fixed. I refused their offer and they called the next day to see if I changed my mind. I refused again waiting to see if there was any fix to this issue on this thread. I have also sent urk a PM and got a simple "got it" reply. Has anyone else gotten any additional info from urk?
Every other game I have works fine as this is the first time I have seen this error. This is my second copy of Reach, and I have verified the disc works just fine in other 360s. The second disc had a DRE in the same place as the first. As it appears there is no solution other than to send my perfectly operational console in along with $119, and there is no way I'll be doing that. I fear the only solution is contacting the BBB and filing a complaint. Oddly enough I can play *one* game of matchmaking if I hit the guide button, sign out of my profile, sign into another profile, exit the menu, pick the storage device, press the guide button, sign out of the profile, and sign into my profile. I'll play one game, and if I attempt to play another I'll get a DRE after the final countdown.
