The firmware is the same as it was with all of 400 burned DVDs that worked until just a few days ago. So I am 99.9% sure it’s a hardware problem. [B]However, I am not sure if there are two lasers, one for reading DVD+ and the another one for reading DVD- media? If there are two lasers, It would explain everything.
Nero 18.104.22.168 might be the newest 6.x.x.x version but 22.214.171.124 and 126.96.36.199 are the most stable ones (as far as I know).
Recently, the DVD tray stucks when pressing [B]eject[/B] after more than a minute since last ejecting. It stucks only at the first attempt of ejecting regardless if the media is or isn’t inside the device. After the tray opens, I can cloce and open it as many times as I want, but after a short delay (maybe a minute, until the motor stops?) the tray stucks again.
I wonder if this is somehow connected with the reading problem :-/
