Teac dv w58e and nero 6.3.1.25

All - getting well brassed of with this dell DVD writer. I’ve checked loads of posts that talk about upgrading firmware and the such and have done this the firmware is now D.0J which is apparently the latest. Nevertheless nero (6.3.1.25 Enterprise Ed) still refuses to accept the *x capabilities of this drive! Any ideas as I’ve upgraded bios/firmware and still no joy :a
