Update to rw8165, can't burn DVD+R anymore

Hi, I recently updated my Ricoh from RW8060 to 8165 in order to burn DVDs at 4x. Unfortunatel I can’t get Nero burning my Verbatim 16x DVD+R disks. Actually I can burn DVD+RW at 2x, but with the +R I don’t even get the option to burn at 2x anymore, only 4x.
So, now, rollback driver or?
