Definetly like Woody said your problem is Nero version, I have a working A05 with hacked firmware 1.33 and everything is working great, my Nero version is 5.5.10.20 and I´m going to stay in that version for a while until I find a reason to change or complaints about new Nero versions stop.guest said:After Update to 1.33 of the PIONEER A-105 I´m not able to erase the medium with NERO 6.0 and Windows XP; now I would "downgrade" the drive to 1.30; but it doesn´t work and the hotline in Germany was not very helpful.
