I think somethings wrong with my Macbooks super drive. In the beginning when copying a music disc the speed started at about 4.0x and increased to about 12.0x where it would finish. But I just popped in a disc to copy and its starting at 4.0x and the farther it goes the lowers it gets, 0.5x is the slowest ive seen so far. Then after listening through the album the songs where the slowest speed was copying the song was all choppy and real screwed up. Maybe its the poor disc quality?
