If you haven't already, you need to enable the Medibuntu repository. The first command below is aimed at Ubuntu Family 8.10 Hardy Heron users and the manual instructions are also, so if you are using a different version of Ubuntu, you will have to slightly edit the command and sources. If you do have to edit the command, you can do so within the terminal by navigating to the word "hardy" with the keyboard arrow keys, change it to whatever version you are running and then move the cursor back to the end of the line before executing the command. Open the terminal (Applications > Accessories > Terminal or KMenu > System > Terminal Program THIS ENTIRE PROCESS WILL TAKE SOME TIME TO RUN. Before anything else do this: [code] sudo apt-get update [/code] [code]sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list wget -q http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update[/code] Now just add these lines at the bottom, remembering to change the Ubuntu version accordingly. After you have added the two lines, save the changes and wget the GPG key as instructed above: [code]deb http://packages.medibuntu.org/ hardy free non-free deb-src http://packages.medibuntu.org/ hardy free non-free[/code] A quick and easy way to install most of the packages you need (Java, codecs for playing/ripping/converting music and video etc) is to use the command line. [code]sudo apt-get remove icedtea-gcjwebplugin openjdk-6-jre && sudo apt-get install alsa-oss compizconfig-settings-manager faac faad gstreamer0.10-ffmpeg gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse gstreamer0.10-pitfdll liblame0 sun-java6-fonts sun-java6-jre sun-java6-plugin pulseaudio-utils unrar w32codecs [/code] For the best DVD playback in Ubuntu, including menu support, install the following packages: [code]sudo apt-get install libdvdcss2 libdvdread3 libdvdnav4 vlc[/code] [code]sudo apt-get install gxine libxine1-ffmpeg[/code] To change the default DVD player in Hardy Heron to VLC (I strongly advise you do), open the terminal and copy and paste this command into it: gksudo gedit /etc/gnome/defaults.list Press Ctrl+f and search for "x-content/video", then change the "totem.desktop" entries to "vlc.desktop". Close and save. Next, navigate to Places > Computer > Edit > Preferences > Media > DVD Video, select VLC and then test whether automatic launch and playback with VLC works for you by inserting a DVD. If playback doesn't work properly, navigate to Video > Deinterlace within VLC and select mode "Blend" Relevant information for you was taken from the Ubuntu How to: MultiMedia Guide found here: http://ubuntuforums.org/showthread.php?t=766683
