While playing Black Ops before going to multiplayer or in the lobby before starting a game or in mid-game a window saying "Unreadable Disc" appears.
The disc dont have scratches and this only start happening after the title update
I cleared the system cache, Clean the disc, re-download the title update the problem still there
I dont think the DVD drive is the problem because i tried other games and no problem only black ops
Please I need help
