Some of the repositories which hold the libraries for mplayer seem to be broken in the Alpha 4 release of Ubuntu 9.04 (Jaunty Jackalope). What’s surprising is that the mplayer installation in Alpha 3 meets all the dependencies and fetches the files correctly, however that for Alpha 4 don’t.
One workaround for vlc is to install libx264-dev, and then install VLC:
$sudo apt-get install libx264-dev vlc
This still leaves unmet dependencies for mplayer.
rick@lithium:~$ sudo apt-get install mplayer
