Recently I found that Nero 6 spoils Audio disks. While converting mp3 into audio disk format it burns three songs and send a message in the log file "illegal disk". The disk is spoiled. Probably, Nero was bribed by the gangsters, who own the music copyright, but more probable it is only stupid bug in the program, in some way linked to the serial number. Nodody knows, except Nero stuff itself. The workaround is really funny. Burn misic files on the CD RW, it works, than copy CDRW on the normal CD. It looks like NERO is being programmed by cockroaches.
