I recently picked up a NEC ND-3520A and I am having speed problems with this drive under linux. A quick "just to make sure" test in WinXP shows that these errors are indeed specific to cdrecord-prodvd and growisofs.

NEC 35x0 drives report crap answers on mode_sense page 2A when DVD media
is mounted. The available write speeds on DVDs can only be requested using get_performance.


cdrecord-prodvd relies on mode_sense at the moment, meaning that it cannot
work with this drive, and growisofs seems to be untested...

GET [CURRENT] CONFIGURATION:
Mounted Media:         1Bh, DVD+R

Write Speed #5:        1.0x1385=1411KB/s

get_configuration is not a command to obtain available write speeds with... which feature number is that supposed to be?
