recently after a small move my 360 stopped playing most games and has been giving me alot of read disc errors. its plays music cd's and movies fine but alot of games thats have seemingly spotless discs will not play at all. some games have stuttering in any MFV segments which i never noticed before and some games (earth defence force) play just fine for some reason. i tried using a cleaning dvd with no results.

its an older system so the warrenty is up/doesn't cover and i don't feel like paying $140+shipping to MS. does this sound like an easy fix i could possibly do myself? i have some experence with opening systems but never a 360.
