Why won't it burn?

I hold a NEC 2510A DVD+-RW drive and i just purchased fujifilm 16x dvd-r discs and im trying to burn a project on them.... the problem is that Nero won't burn them because it say that it doesn't support the type of discs but this website tells me that my drive supports it:

So is the website wrong or is Nero?

and what should i do?

should i merely buy different discs....?

Why won't it burn?

That comes down to experimentation. Check whether another program will write to those discs. I have run into such a problem near DL discs (-) and the error that came up be that it needed (+) discs instead.
