09/11: release-packages for RPM Fusion's EL5 repositories available
You can enable RPM Fusion's repositories for EL5 with this easy command now:
rpm -ivh http://download1.rpmfusion.org/free/el/updates/testing/5/x86_64/rpmfusion-free-release-5-0.1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/testing/5/x86_64/rpmfusion-nonfree-release-5-0.1.noarch.rpm
Note: RPM Fusion for EL (RHEL/CentOS/ScientificLinux/...) is still in the testing phase and still lacks some packages we'd like to see in those repositories.
Further: The repository is meant to be used on top of EPEL (which itself is meant to be used on top of RHEL/CentOS/ScientificLinux/...). Right now some of the packages in the RPM Fusion EL repository require packages from EPEL-testing, hence you need to enable EPEL-testing as well until EPEL moves them to the proper repos.
