Nec 2510a -- memorex dvd-r 16x

Hey, I’m using a nec 2510a burner with nero. I have used memorex 8x dvd-r and memorex 16x dvd+r with this burner before using the nec 2.15 firmware without a single problem. I buy a new pack of memorex dvd-r 16x, and now nero keeps telling me it’s illegal media when trying to burn one of these things. I updgraded the firmware to the nec 2.18 and still no dice, I’ve also tried using the mad dog ones too. Anyone have any ideas?

The 2A5C firmware from http://liggydee.cdfreaks.com/page/2500/ might help.
