Powers and Principalities.
Like mnewsham, I have three different Blu-ray drives, two of which are BDXL (one old, one new, both Blu (LOL)). Every UHD Blu-ray that I have bought can be read and copied to my server by the BDXL drives, but the encryption makes it impossible (currently) to play the files back. At this point I really have no idea if it will ever happen - be it officially supported software or unofficial crack. I have contemplated buying a HDCP stripper, but the process of playing back in realtime for capture, then re-encoding the capture into a comparable size with the same quality and HDR metadata seems like a lot of effort this early in the game.
