i bought my xbox in january this year. i only have four games for it so far but jsut recently it has developed a problem, it has put a deep scratch neatly all the way round everysingle one of my games. i was just playing multiplayer when a notice poped up and sayed "disc unreadable" please clean the disc. when i pulled the disc out i found the neat scratch and i thought it was a one off but then it done it to another. so i stopped playing it but without me knowing my brother carried on playing the other two games and scratched them aswell. i did not move the console at all. please help me and post any advice thank you.
