DVD Playback on Gutsy

Configuring DVD playback on Gutsy

For DVD playback, install VLC (accepted by most as the best DVD player, supports menus too);

sudo apt-get install vlc

And if you also want Totem to play DVDs well, you have to use the Xine backend instead of Gstreamer (this is optional, VLC will do just fine);

sudo apt-get install totem-xine libxine1-ffmpeg

To get encrypted DVDs playing properly (check out no. 9 in the "Troubleshooting" section if you are having problems with new DVDs), paste these commands into the Terminal;

sudo apt-get install libdvdcss2 libdvdread3 libdvdnav4 build-essential debhelper fakeroot

then;

sudo /usr/share/doc/libdvdread3/install-css.sh

or if you get an error with that command;

sudo /usr/share/doc/libdvdread3/examples/install-css.sh

To set VLC as your default DVD player (I strongly advise you do) type the following command into the Terminal;

gksudo gconf-editor

Now expand "desktop" and then "gnome", scroll down to "volume manager" but don't expand it, just click on it and look over at the right pane. Scroll down and look for "autoplay_dvd_command" and change the command to "/usr/bin/vlc dvd://" (without quotes of course) by right clicking on it and selecting "Edit", then click on "Set as Default". Do the same for the "autoplay_vcd_command" as well.
