NEC DVD +/- RW Model ND 3530A - Firmware support for -R Dual Layer burning

The ND 3530A currently supports burning +R Dual Layer DVDs but not -R Dual Layer DVD's . Now that -R  DL discs are becoming widely available, do Dell have any plans to release a firmware update that will support  -R  DL. ?

 

Failing that has anyone used third party firmware that updates to enable burning  -R DL .  If so, does it work and where can I find it ?

 

Thanks Rich
