I want to buy some blank DVDs to start making back-ups of my data. My question is, who makes the highest quality ones? We have TDK blank CD-R's because I kept hearing they are one of the best in blank media. What about for blank DVD's? Also, should I get blank DVD-RW's or DVD+RW's? Is there a difference? Does one work better with Macs or DVD players in general? Is one higher quality?
