Nec 1300a doesn't write to dvd-r from SKS

writing to a dvd-rw (other brand) goes excellent, nero burns with 2.4 speed
But when I try to burn to a dvd-r (from SKS), nero immediately gives an error: Burning failed at 2,4 speed, other speeds don’t work too.
I use normal 4x dvd-r disks (SKS) and my burning device is a NEC DVD RW ND 1300A

anyone an idea?

First step is to make sure Nero is updated :bigsmile:
Newest current 6.x version is 6.1.3.6

You should also update your firmware, newer firmware versions usually support more media and increase media writeability. The newest 1300A firmware is 1.0A
