Just struggling a bit with types of disk. If I go into explorer , my D drive shows as a DVD -RW drive. The label on the actual drive says its DVD + rewritable DVD +R DL. I believe that means I should use DVD -RW disks ? However , with bad advice, I bought some DVD +RW disks, and have somehow managed to save, via Nero, some video footage ?! So could somebody kindly answer these for me , as I keep getting conflicting advice, thanks. Assume Im going to be copying to DVD via Nero, though may move to Pinnacle. Thanks a) Should you have to format DVD +/-RW disks first ? b) When copying files to DVD RW, do you have to somehow select to not finalise in Nero, to ensure you can write to the DVD again? c)How did I manage to write to DVD +RW ?! Many thanks in advance.
