    There are PRC region free firmware available for this drive that you can download and install in windows. I'm wondering if this will affect osX. I'm reluctant to do it, has anyone else updated the firmware of this drive?

    That firmware is RPC2, not RPC1 (Region Free).

    Region Protection Control.

    RPC 1 is bypassable by VLC etc, if not hacked to be completely free.
    RPC 2 isn't...

    Correct me if I'm wrong! :)

    The essence is correct, but AFAIK not all RPC-2 drives disable raw data access. IIRC this only became an issue with the most recent hardware revs, and earlier Macs still had RPC-2 firmware, but worked with VLC.

    RPC-1 left it up to the software to decide whether a disc was playable, while RPC-2 firmware will not let the software have the data if the region code is wrong.

    Does that mean that the UJ-845 will read/write DVDs that the UJ-846 won't?
