I have a NEC 1300A dvd burner. I tried backing up this game twice using Nero 5.51050 Enterprise Edition with dvd-r's. It said the burn was successful but when I tried it in my PS2, the game worked but I didn't have any sound. I already backed up some other dvd games using Nero and they worked fine. I also tried burning it with Alcohol 120% v188.8.131.521 but I kept getting a disc dumping error. What does that mean? How do I back up this game? Thank in advance.
