Francis managed to create an updated version of the 1-click-installation for codecs in the latest openSUSE 11.0 RC1. This will be at the exact same place at the old link, as 1-click-install gives you the possibility for different preferences for different distributions. So here are the links:
This will install things like DVD and MP3 support, Win32 codecs, flash and java (if you installed from the live CD), unrestricted xine codecs (for DiVX etc.), as well as the latest Amarok and K3b codecs (for the KDE ymp).
