i recently bought a refurbed emac... everythings great except i just tried my life dvd yesterday... and it doesnt work. the drive makes weird noises and the dvd doesnt mount. i know its not the drive, ive been using it fine since. i tried the dvd in my buds PB and it does the same thing. no noticeable scratches on the dern thing either..... any ideas? think apple would send me a new one??! or maybe a g5 since ive gone through so much pain.
