Is the current status regarding UHD BD protection that e.g. MakeMKV can decrypt all the disc that exists as long as users submit "dumps" for discs currently not supported.MakeMKV is using their own aacs2.0 dumps to retrieve title keys. Has nothing at all to do with deuhd. They aren't using it to get the keys. The hashed key list already had several titles not supported by deuhd and that list is about to grow as more users submit aacs2.0 dumps created by MakeMKV.
Than would make AACS2 practically useless at the moment. That may change though when BDA realizes the big picture. I find it strange that nothing seem to have happened yet. No studio suspending releasing till further notice, no BD+ kind of extra protection like what happened in the early days of standard Blu-ray. No revoking of keys. I guess it would hurt whole slowly rising 4K UHD BD business too much.
I tried MakeMKV method during the weekend and backuped my copy of Deadpool. Remuxed main audio and one set of subtitles to mkv file. Worked fine and took only 35-40 mins. I have a BH16NS55 1.02 drive.
