NEC ND6500A DL Burn problems

I have a Dell Inspiron 6000 running Win XP-Pro. It has a NEC ND6500A that came with the laptop. It has no problems with burning CD’s or DVD5, but when trying to burn DL. It fails when trying to burn first layer. I am using Nero latest, and the media is FujiFilm DVD+RDL. The laptop is still in warranty and I am trying to solve this issue before it runs out. Dell is no help.

Are there software issues here, possible conflicts,(I also run Alcohol on same machine), firmware issues. The Dell software people seemed to think it was a simple fix, but wanted mucho dollars to tell me what it was.

Please help
