Hi, I've had my MacBook since February last year, it's the late 2007 model with a 120 gig harddrive and 1 gig of ram (I've updated the ram to 2 gig) Anyway the superdrive is suppose to be able to burn DVD's at 8x right? Mine can only burn DVD +R 16x dvd's at 4x! If i remember correctly i have burned discs faster on this machine before but now i can't Oh and i'm burning with Disc utility and i mostly burns .img files. Anyone have a solution to this? Any help is appreciated!
