Surely most of you have some, if not many, movies on DVD and you are used to watch them on the PC.
Unfortunately, due to licensing Ubuntu is released only with free codecs for multimedia playback and therefore it requires few additional steps to have the codecs for proprietary formats (DVD, mp3, avi, etc.).
If you want to play DVDs you have to install the dedicated library named “libdvdread4. To do this just open the terminal and type:
sudo apt-get install libdvdread4
After few seconds the last command will confirm that the installation is complete and therefore you are able to play any DVD with your favorite media player.
