I have had no problems with my 106D burner, but upgraded because it did not support 8X DVD-Rs or higher. I now find that with my new 110D burner, I cannot burn 4X DVD-Rs at 4X speed without error, but I can burn them at 2X speed. Nero 6 appears to burn it OK at 4X speed, but on trying to read it afterwards, the drive hangs. It appears to write 8X DVD-Rs at both 4X and 8X speeds OK, however.
I also find that I cannot burn a 1-4X CD-RW at 4X speed, but after erasing it, I can burn it at 2X speed. I get the same problem that it appears to burn OK at 4X speed, but the drive hangs when trying to read it.
I have upgraded the firmware to version 1.17 with no apparent effect.
Does anyone else have this problem?
