Can't Play Video

Hi how can i play video files (divx),, because when i try to play something, it writes

"Search for suitable codec?

The required software to play this file is not installed.
You need to install suitable codecs to play media files.
Do you want to search for a codec that supports the selected file?"

And then is shows repositories with codecs, but for 10.3. So where can i download right codecs?

openSUSE is provided crippled for proprietary codecs (for legal reasons). Take a look here:

I actually recommend you FIRST update your repositories in YaST following the very brief and to the point guidance here:
