Yes, only windows has a good driver for JM20336
So cdrecord will work after Jörg prepares his
workaround for the LG drive firmware bug. :-D

Okay, I tried it and it worked with JM20329 chip.
And growisofs did negotiate 2x speed properly.
It only took 17 minutes to burn 8.7 GB.
See results below:

$ growisofs -Z /dev/scd0=image.iso -use-the-force-luke=spare:none
Executing 'builtin_dd if=coxdj_20091030.iso of=/dev/scd0 obs=32k seek=0'
