Mplayer is my default media player, and I recently caught an episode of “Jericho.” CBS boasts that you can watch their full episodes online. I have had the deuce of a time trying to get these to work.
To make a long story short:
1) download/install latest RealPlayer for Linux.
2) copy everything the newly created from codecs directory and plugins directory into /usr/lib/win32.

Done.
