Cinavia is a different story - it's not a form of encryption. It is an audio "fingerprint" that is added to the BD, and it ONLY works if you use a player that respects it... and most devices and programs that handle MKV files do NOT look at Cinavia.

MakeMKV removes the encryption from the video/audio.

A Blu-ray player (a device) is supposed to validate Cinavia no matter the source. But, there are some Blu-ray players that do not check files. Unfortunately, Samsung is a manufacturer that does validate Cinavia, no matter the source.
