Interesting that something is happening in this area again. Why are you sending a REPORT KEY command first and then the READ DISC STRUCTURE? The key isn't used later, and why do both commands use a different AGID (00b vs. 11b)?
Hmm, the GGW can do 6x BD-R writing while the PX only 4x, i would be careful to use the PX firmware on the GGW.
