Enable DVD Playback in Ubuntu
Ubuntu doesn’t play DVD from a fresh install. You need to install a few programs and codecs first. Here is how to do it: sudo apt-get install totem-xine libxine1-ffmpeg libdvdread3 sudo /usr/share/doc/libdvdread3/install-css.sh That’s it! Enjoy your movie! (source: tech-recipes.com)
