I've been downloading DVD's for a few months now. After I burn them they will play fine in my PC and also on my portable region free DVD player and even on my friends Deawoo Region 1 player. But some of them will not play in my stand alone Sony DVP-NS72P player. I'll get an error saying "prohibited by area limitations". These DVD's have already had Macrovision and RCE protection removed ( I even tried ripping and burning them again with the latest ver of DVDDecrypter) And they are also NTSC not PAL. My stand alone player also plays DVD-r's well. I haven't had any trouble backing up any region 1 DVD. I know somebody out there must have this problem too. Any help will be greatly appreciated.
