Pioneer DVR-216MBK

How does the Pioneer DVR-216MBK differ from the DVR-216DBK, other than the Q-Flix feature? Can the MBK drives be flashed to DBK? A quick check of several of Pioneer’s firmware download sites not only shows no updated MBK firmware but no mention at all of the MBK. I have no use for the Q-Flix feature, so I don’t mind losing this feature if Q-Flix is in the MBK firmware and it can be flashed to a plain old DVR-216DBK.

Has anyone done this successfully?
