Is this possible? My PB surely reads DL DVD+R but i have no idea if it can read DL DVD-R. Attached is that what kind of dvd it is fro system profiler but i have no clue from what it sais if its DL DVD-R compatible! Heck if i wouldnt of tested it reading those specs would make me think its was incompatible with any DL dvds. Correct?
