I recently bought gears of war 3 and the majority of the time it says disc unrecognised or open tray however this is the only game this is happening with (that I have). DVD's and CD's play fine too. The disc is clean and i have tried several copies of the game all have the same problem. I have also tried playing without the hard drive and clearing the chache and still the problem is there. I have had several xbox's that all died from different problems and there is no way I will pay for a repair or a new console just for one game. Any suggestions?
