BluRay support
      
      The VLC media player
          in Fatdog64 can support BluRay playback. For that to work you
          must install a file containing the keys. The name of the file
          is 
KEYDB.cfg and is placed in
            
~/.config/aacs/. The KEYDB.cfg file
          provides
processing keys and a host key that provides
          decryption. The processing keys are changed occasionally. The
          revision of the processing keys corresponds to the
Media Key Block (MKB)
          version. Currently there are KEYDB.cfg files that support up
          to MKB version 30. Another optional file named
            
vuk
              which would
              also be placed in
              
~/.config/aacs/,
          contains keys that are specific to a particular disk. The vuk
          keys can also be combined into the KEYDB.cfg file.
          
          
Steps to play a BluRay in Fatdog64:
          
          1) Check your local laws to see if it is legal for you to play
          the disks that you own. Sadly that's not a joke.
          
          2) Find a 
KEYDB.cfg
          file and put it in ~/.config/aacs, for most users you'll have
          it here:  
/root/.config/KEYDB.cfg
          
          
          3) Click on the optical disk icon on your desktop. VLC should
          play the Bluray.
          
          If it does not play it probably means that your KEYDB.cfg
          doesn't have a key to support the MKB version of your disk.
