Has anyone been experiencing this?? I have a 2Ghz macbook pro and I get verification fails after every burn I do. I tried using Toast, some other free burning utility and disk utility. Fails on each program. I even tried other brands of dvd's. They only thing that worked was to slow down the burn speed to 1x. This takes about an hour to burn a disc! I was wondering if I need to clean my optical drive? I used to clean my cd burner back in the day if it started failing burns, but my computer is only 1 yr old this month and it is usually usually on my desk. Anyone else having these problems?
