Some openSUSE concepts to brush up on: Concepts - openSUSE - THATS IMPORTANT !!
You could also skim thru the applications on the packman page, before installing openSUSE, to get a flavour as to what 3rd party multimedia apps are available as pre-packaged rpms (read the concepts page to understand what an rpm is). PackMan :: home
Also, BEFORE burning your CD for installing, read this stickie:
NEWBIES - Suse-11.0 Pre-installation – PLEASE READ - openSUSE Forums
My recommendation is after installing, the 1st thing you do is get internet access. This may work immediately. It may not. Give it priority.
2nd thing I always do is set up my Software Package Manager (SPM) repositories to make software installation easy. Read the concepts page to understand what repositories are.
I recommend you setup 4 and only 4 repositories. Specifically only OSS, NON-OSS, Update and Packman. No others. None. When you learn more about the risks of others, then and only then can you add others. Guidance for adding your repositories is here: Repositories/11.0 - openSUSE-Community
Again, only OSS, NON-OSS, Update and Packman. No others.
3rd thing (with repositories setup) is install a minimum of high quality multimedia. Note you need to replace Novell/SuSE-GmbH packaged multimedia apps with many 3rd party packaged replacements (typically packaged by Packman). Typically one simultaneously should replace Novell’s xine-lib with Packman’s libxine1. Remove one and add the other AT THE SAME TIME. Don’t try to do it separate. Also, replace Novell’s packaged amarok/kaffeine with Packman’s amarok/kaffeine. Apps I always install include smplayer, mplayerplug-in, libxine1, kaffeine, vlc, libffmpeg0, w32codec-all (plus many others)
I also install libdvdcss2 from videolan. (But only libdvdcss2 and no others from videolan, as others have been known to interfere with Packman packaged apps).
Note many audigy users struggle with their mixer. Take note of this guide:

Good luck.
