i wanted to make dvd copy of a copy and i am getting a unrecovered read error. i am using roxio dvd copy to do this. I dosent matter what burner i use the one is a lite-on SOHW-8325 and the other is a sony DRU 530A i receive the same error on either one. I have tried several other dvd coping software and no luck. Is there any other software that might work or am i doing something wrong?
