I have tried to back up killzone loads of times now and every time I have failed (I have never copied a game before). First I just copied it normally but I know now that shouldn’t have worked now anyway. Then I used DVD decrypter and it worked, the game was going fine but next time I tried killzone again and it got stuck when it was loading at the start. So I tried it again on a 1x speed and I got not ps2 disk or something. Then I tried it on alcohol 120% and I got the same message. This is really annoying me now does anyone know what I could be doing wrong?
