I have now surely burned 40 DVD's and this type had been not a single "false fire". Software: Nero6 Brenner: BenQ DW1640 Speed: 8x; 12x and 16x These blanks erziehlen in the Disc Quality-checking with "Nero CD-DVD Speed" a quality score of 100% at 8x and 98-99% at 12x and 16x. Combined with the BenQ-burner, I can only recommend this blanks.
