I received this from a friend, and thought I would post it here in case anyone would find it useful.

After Installing Ubuntu, basically I do this:

Go to:
System -> Administration -> Software Sources -> Other Sofware, and enable partner repository.

After that, we can this on a Terminal:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install ubuntu-restricted-extras
sudo /usr/share/doc/libdvdread4/install-css.sh
