MPlayer and DivX

Hi all, When I was installing SuSE 8.2 I selected the package MPlayer and KMPlayer, at the package description said that this program supports DVD. VCD and DivX. Now I'm trying to run a DivX movie (that works on Windows using the DivX codec) under MPlayer and it just doesn't work. Do I need to install any other package from the SuSE CDs?, or do I need to download the DivX codec from www.divx-digest.com ?. Isn't the DivX support already included? Thanks Ernesto
