Playing Encrypted DVDs in Ubuntu

By default, Ubuntu doesn't install the necessary software to play encrypted DVDs for legal reasons. In order to play them, install the following software:

sudo apt-get install libdvdnav4 libdvdread4

You might also need the following if they are not already installed:

sudo apt-get install gstreamer0.10-plugins-bad gstreamer0.10-plugins-ugly

After this, run:

sudo /usr/share/doc/libdvdread4/install-css.sh

Enjoy your DVDs!!
