First of all, why do they sell dual layer burners with lightscribe, but not dual layer lighscribe media? Anyway, so I tried to burn a dual layer DVD through Toast 6.1.1, and the first time, the program just froze at the end, and the second time, it froze and then said there was a problem with the mac OS. It's an HP DVD 840 and i'm running a MBP with OS 10.4.7 and a gig of ram. Anyone know what might help? Thanks!
