A lot have been said here about DVD-R discs, especially Verbatim and TY brand, for being better to use for back up than DVD+R format. I tried both of those brands using DVD-R disc but kept getting problem with copying the games or my PS2 can't read the discs. Then I tried the Maxell DVD+R and Sony DVD+R, and surprisingly, both of them worked! I am still trying to figure out why I can burn and play DVD+R but not DVD-R games. Does it have anything to do with my DVD burner (Sony DRu-800A)? I just want to be able to use my DVD-R discs instead of having 100+ of them laying around. Thanks for your feedback!!! I have a silver Slim PS2 (V15)and using DVD Decrypter and have Magic Keys 2 with Magic Swap 3.6 Plus. The games I have backed up so far play beautifully.
