other option can be to "induce" RROD if you're still within the 3 year special RROD warranty. i dunno how you'd do this, but i'm sure it's possible. i think it has to do with overheating the system, like leaving it playing a game for a few days straight. i was having DVD drive issues for a about a year (cant read disk errors all the time) and when i left my last job had a few months of nonstop playing for long stretches of time. Got RROD in about 6 weeks, lol. anyway, shipped it out for RROD repair (2nd time with the RROD), and got a "new" console this time. no more DVD drive problems.
