If you want to have a movie player after an install, you might want to install VLC media player. But found version in Synaptic is 0.8.6,
old.
I did the following (from a guide somewhere on the internet):
In terminal type:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7613768D
In Synaptic go to Settings->Repositories
add
deb http://ppa.launchpad.net/c-korn/vlc/ubuntu/ hardy main
add
deb-src http://ppa.launchpad.net/c-korn/vlc/ubuntu/ hardy main
After adding those two sources press Reload.
After a search on
vlc you will find vlc media player version 0.9.9a
If someone knows a better way, I missed something, a guide for installing version 1.0 just answer this post.
[edit]: If you have version 8.6 allready I think you have to fully uninstall that version before installing 0.99.
