DVD's used to play with 12.04, but since I upgraded to 13.10 I can't get any type of dvd to read. I have tried Totem and VLC. I have also installed the following:
sudo apt-get install gstreamer0.10-plugins-ugly gstreamer0.10-ffmpeg libxine1-ffmpeg gxine mencoder libdvdread4 totem-mozilla icedax tagtool easytag id3tool lame nautilus-script-audio-convert libmad0 mpg321
and
sudo /usr/share/doc/libdvdread4/install-css.sh
