I'm having problems with my dw822a burner. The burning process just hanged at 9% on dvddecrypter. The Led light goes off after that. After I closed the program, my computer becomes really laggy. The burner does not work even with a reboot. It only works when I turn off/on the power supply. I tired changing the cable but it didn't work. I had wasted 4 dvd+r trying to fix this. All of process hanged around 9%-20%. Should I replace this burner?
