Nec nd-2500 problem with moser baer



So far i’ve been backing up games using DVD+R in my NEC ND-2500 burner.

Now i’ve moved up to DVD-R Moser Baer Memorex discs to back up games and Nero says they’re illegal discs so I systematically installed all of the firmwares from Liggy and Dee’s site.
All of the firmwares managed to make my burner fail to find the disc in the drive.

So my question is; Is there any firmware out there that is compatible with Moser Baer discs? or is the drive dead now?

I get this from dvd identifier

Buy a new burner or Verbatim discs, your burner is obsolete.
