I have bought a new DVD burner that can write dual layer DVDs, the NEC-3520. I haven't got it yet or the ST DVDs, I heard these are dual layer, so my question is. Does anyone have any experience backing up TNG, VOY, or DS9 DVDs? What do you recommend I do? Should I buy dual layer DVDs? I can't seem to find many and they are all +R (does it make a difference?) If I were to use DVD+R DL would it work in most modern players? If I were to just put it on a DVD-R signle layer is that even possible? Or are these DVDs too large? What do you guys recommend I do? Thanks for any help you can give me.
