Movies with Lionsgate Playlist Obfuscation copied disc detection won't play (correctly). - With BD-J Menu BD players will when playback is started run straight into the "copied disc detected" message displayed for 1 minute and next return to the Main Menu. This is what frankly all BD-J enabled BD players will do as this response is embedded within the Java code. This FW in fact also fails the BD-J menu processing to do so and simply will get stuck there instead. - Without BD menu it falls into the playlist obfuscation trap and plays a wrong playlist sequence just as many other BD players do too. A few players will know to select the correct playlist though. Example: Lionsgate "Knives Out UHD". Please don't confuse this with Cinavia as it is a different protection (that one resides within the audio track).
