Nec 3650a dvd+r dl booktype

How do I change the booktype settings to dvd rom for dvd+r dl discs with my nec 3650a burner?

thanks

Depends on your burning app. Which do you use?

I use imgburn, but when i try to change the booktype in that on the nec tab it says
Unknown (Failed!)
Reason: Invalid command operation code

the necwinflash.exe program lets me change the booktype for dvd+r sl and dvd+rw but not dl

OK, then go to liggy&dee’s site and download an approriate firmware with Bitsetting enabled, also download necflash.

I am already using the 108c rpc1 firmware from http://liggydee.cdfreaks.com/page/en/NEC-ND-3650A/

necflash gui says dvd+r dl bitsetting is not available. Is there no way round this?

Is there a different firmware i should be using?

thanks

Check the drive properties using dvdinfopro or nero infotool.
