Unfortunately due to copyright laws, Ubuntu is not allowed to have certain audio and video codecs installed by default. However, they can make them available after installation. Try these steps:

Add the medibuntu repository:

sudo wget http://www.medibuntu.org/sources.list.d/[your_distro].list --output-document=/etc/apt/sources.list.d/medibuntu.list

Replace '[your_distro]' with your distribution (i.e. jaunty for 9.04, karmic for 9.10, etc)

Import the gpg key. You will receive a message saying the source could not be authenticated (or something like that) just say yes.

sudo aptitude update && sudo aptitude install medibuntu-keyring && sudo aptitude update

Install the w32codecs package and ubuntu-restricted-extras

sudo aptitude install w32codecs ubuntu-rectricted-extras

All done!

You may also want to check out this guide. Its a great help to new Ubuntu users who want a functional desktop with the most typically used software. (This is where the above came from. I know its for 9.04, but if you follow the above when adding the medibuntu part, you should be ok with any other distro from ~8.04-9.10.)

enable your backport by editing: sudo gedit /etc/apt/sources.list

uncomment the line: #deb http://archive.ubuntu.com/ubuntu/hardy-backports
main restricted universe multiverse (simply remove # before deb)

...save and exit, then sudo apt-get install ubuntu-restricted-extras...you can re-edit sources.list if you want to, and mark the line which you formerly unmarked. (i assume you are using hardy, if not so just change the word hardy to whatever version you are using...intrepid or whatever)

...patience is the key to everything, take your time. what version of ubuntu are u in? make sure that you have edited sources.list correctly.

[byStanderone]

...ok, we'll do it thru another way, download and install the restricted extras from http://packages.ubuntu.com/jaunty/ub...tricted-extras maybe this would start-up things at the moment.
