3540A won't record past 2.4x

I bought a new NEC ND3540A, it says it records up to 16x DVD+R, I have 2 50 packs of JVC DVD+R 1-8X discs, everytime I try to record onto those DVDs, it only lets me record at 2.4x. I use anyDVD with CloneDVD2, and I also have nero, but it won’t let me select the burn speed, and it’s stuck on 2.4x. any suggestions? :a :a :a

Those discs are not supported in the current firmware.
Hence the 2.4x generic writing strategy.
Post the MID.

you can’t select a burn speed without a disc in the drive in nero
