no reason at all to verify with nero. run the md5s and or test the ffp's. takes way less time and it does all you need it to do. glad you got it worked out. 99% of the time these type of things are firmware. I just got a new laptop. the burner was suppsoed to be 8x dvd and 24x cds. well cds would only burn at 8x even though it said 24x. dvds all I made were coasters. new firmware and it works like a champ.
