I am using openSUSE 10.3 and enabled multimedia with the help of 1- click install . what i did was searched for the relevant player like vlc, mplayer etc. and the codecs like divx, libdvdcss, xine-lib etc using the software search function present at
*packages.opensuse-community.org/ and *software.opensuse.org/search
and got everything working on my installation . I can now play all the formats that i was enjoying with my Win XP..... now SUSE rocks and does better than MS winDows.The beauty of 1-click install is that it downloads all the dependencies and the make the app fully working. Just be sure to get yourself a reliable internet connection. I had faced severe problems because i don't have broadband at home and had to rely on a GPRS modem
