If I am going to be backing up my DVD movies, which type of DVD+/-R(W) should I be using? I am using a burner that can burn both formats (Sony DRU-540A) From what I have read, DVD-R/RW are the standard and DVD+R/RW is a newer format. Is it true that DVD-R/RW are slighlty better in terms of playability in standalone (regular) DVD players? Basically, should I be opting for DVD-R/RW or DVD+R/RW for my DVD movie backing up purposes? Furthermore, should I be using R or RW disks? Thanks!!
