i recently got a dvd burner and backed up about 4 gigs of data. It took 1 hour and 14 min using nero 6 going at "4x." the media, -R, said it supported 1x-4x. Is this how long its supposed to take? i've looked around and i can't seem to find any information. is there anything i can do, or undo to make it write faster? thanks in advanced.
