I bought a secondhand Philips DVDR70 DVD Recorder (Code 2). I came home and tried to play a Reg1 DVD. It said it cannot play because the region of the disk is 1 (Not codefree). Then I applied this famous "212 121..." region hack and after that I couldn't play both Reg1 and Reg2 DVD-Video or DVD-Rs. I can't go back to original code either since I don't know. Anyone here to help. Playing Reg2 DVDs will be enough. Playing Reg1 and Reg2 will be appreciated. Gruss aus der Schweiz.
