Error writing DVD+RW media with ND2500A

I cannot write to DVD+RW media I have tried with SONY DVD+RW 4x and TDK DVD+RW 4x. DVD-RW 2x is working and DVD+ media.

I have been working before and it stopped working at some point. It could be after uppgrading to Xp SP2 but I am not sure.

Is there anyone else that have problems or should I contact Nec for support?
