Ubuntu Media Codecs

To install codecs to play back mpeg 4 video files I followed the instructions here http://linuxowns.wordpress.com/2008/02/11/media-and-ubuntu/ for Ubuntu 8.04

$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

#DVD support
$sudo apt-get install libdvdcss2

#Some mpeg 4 codecs
$sudo apt-get install w32codecs

#Other codecs
$sudo apt-get install non-free-codecs
