I just got a burner and went out and bought some blank DVD's without even researching. I bought 25 Memorex DVD + R 4x for $25, backed up a DVD and it didn't work. I changed the burn speed to 2x and now it works fine on my PS2 (version 10). It also works on my Goldstar DVD player I bought 4 years ago that I didn't think supported DVD+R. Is this a good brand to stick with and can I use cheaper media?
