I understood that the NEC2500A being one of the newer drives could possibly be updated to burn dual layer.
If the pioneer A06/7 has been tested with a firmware update, (and it works) then is it physically possible that the NEC2500A can be modified either officially or unofficially with a firmware patch ???
I really hope so !
Any information on this would be interesting (I contacted NEC and they would not comment on anything. Other than no plans yet)
