If you were experiencing some problem trying to play commercial DVD’s in Ubuntu now your problem would be resolved (hopefully).
- open “terminal”
- type
sudo apt-get install totem-xine libxine1-ffmpeg libdvdread3
- then type
sudo /usr/share/doc/libdvdread3/install-css.sh
Now play a DVD in your computer that it didn’t work before to see if it works. Thanks to Tech-Recipes.
