Can it be done? Using Singapore Verbs, i've made two coasters using DVD+R DL discs, on the dashboard all i get is 'mixed media disc'. Using DVD-R DL Verbs i get 'unreadable disc'. All discs burnt using imgburn. Not sure what the problem could be, i used to be able to burn games fine on my old drive, however this new Laptop and Matshita drive seems to be giving me issues.
