Nero - DVD rw failed - Illegal Disc @ 1%

I updated my nero burner software to upto date and I did update the Liteon firmware to the latest one. But I am still not able to write DVD ([bold]4x rw rewriteable DVD does not work but 1-8x DVD works fine[/bold]), not sure what is the problem.

Here is the log. Any help please.
