You could simply download the RPM from http://tettnang.freshrpms.rnet.
if you take that road log in as root or type "su"
the rpm -Uv mplayer-1. (press tab)
it will undoubtedly spit back dependancies that aren't met but everything you need is at the same site you downloaded the stuff from.
hint it might tell you something like that it needs fame, libfame.so and libfame1.so. All of that will be gotten with thew fame package.
also mp3lame will be put in with lame
You don't get as many options with rpm, but it usually works pretty well.
