Change booktype on DVD Decrypter on NEC failed

I am trying to burn a movie using DVD Decrypter. I am using a Dynex DVD+r media. Unfortunately my dvd player does not support +Rs, so I tried to change the booktype on DVD Decrypter, but it wont work.

I have an NEC ND-3540A with 1.03 version firmware. Can anybody help. thnx.

NEC’s stock firmwares do not support Bitsetting on DVD+R. You need to download a bitsetting patched firmware for your drive.
