i got an error when ripping final fantasy 12. it stuck at 8%. it says failed to read sectors. is it because my original media is bad? i had no difficulties playing the game with my ps2 and no stuck. but when i rip it, it stuck at 8%,something like 338MB. tried using nero, stuck at 4%, using dvd decrypter stuck at 8%. is it my source already is a bad disc?
