DVD-R Verbatim 16x Detects As DVD-RW in Nec ND-4550

Hello!

I burn a DVD-R 16x Verbatim (MCC 03RG20), and now the my nec nd-4550 recognizes the dvd as dvd-rw, and in the Nero CD-DVD Speed not allow to scan the quality test. Somebody can help me to solve this problem ?

What software have you used to burn it?
Have you set a booktype?

Is a software like Alcohol instaled?

I burn with nero 7.5, the booktype is Automatic, i have original fw 1.09 for nec nd-4550

the exact same thing happened to me with my nec 3550 and dvd+r disks burned with nero and imgburn and bitsett with both, 2 blow outs with compressed air temporarily solved the problem, I finally disassembled the drive, finding a film on the laser lens(probably from outgassing of a white goop that was on one of the chipsets)
