There are fascinating legal reasons that repositories like 'rpmfusion'
might not be in the Scientific Linux defaults, and certainly reasons
why it's not enabled in the upstream RHEL defaults. Checking the
public web pages about rpmfusin, the RPM are listed at
http://rpmfusion.org/Configuration

Once you've installed it once, it'll be available from then on on that system.
