I got a sony dru-540A working on a P4 w/512mb. when I started burning, it would take me like 10-20min to copy a burned dvd. Ever since I tried to back-up FORGOTTEN (which ny the way I couldn't using shrink and anydvd), it is taking me an avg. of 1 hour to copy a dvd I already burned. I checked my device manager, re-intalled my driver, re-installed the software (nero 6) re-installed the burner, de-frag the system. I dont know what the hell else to do. If any-one has any suggestions I'm game!
