Now let us see how to configure Ubuntu Linux to play encrypted DVDs .
Most DVDS comes with Content Scramble System (CSS) which is a Digital Rights Management (DRM) scheme. The CSS key sets are licensed to manufacturers who incorporate them into products such as DVD drives, DVD players and DVD movie releases. Most DVD players are equipped with a CSS Decryption module. CSS key is a collective term for authentication key, disc key, player key, title key, second disk key set, and/or encrypted key.
In order to play encrypted DVDs just install CSS library with following linux command
First install open source Linux player such as vlc or xine, mplayer etc using apt-get command:
$ sudo apt-get install vlc xine mplayer libdvdread3
Now install CSS library:
$ sudo /usr/share/doc/libdvdread3/examples/install-css.sh
Now you can play DVD by visiting Applications > Sound & Video > Movie Player > Select player menu option.
