Well, It can be a little tricky at first... so you went to:
http://easyurpmi.zarb.org/
Just make sure you choose the correct MDK version and Architcture...
I would suggest doing one source at a time and cut and paste the URL to your root terminal from there...
I would suggest "contrib", "main" and "plf-free" first...
Then after updating try from a root terminal:
# urpmi mplayer
You get the idea...
