I have a total of 5 games for the xbox 360, two 2K sports games (NBA, MLB) and 3 with EA games (Maddon 06, Tiger Woods 06, and now NCAA 07). This may sound strange but only the 2K games are working completely as I'm able to play full game modes with no interruption. However, on the other side of it, the EA games are giving me error codes continuously saying "Disc Unreadable." I've already sent the system back to microsoft and they're telling me the disc drive is fine. I called EA games and informed them of the situation, said it can't be the game, but you can send them back if you want. Sooo, now what? Does anyone know of or had problems of this and what might be the solution? Thanks!
