No source repositories for updates?

When I try to use "yumdownloader" to get a source package, it replies with an error message: mimmi$ yumdownloader --source x264.x86_64 Enabling updates-source repository Enabling rpmfusion-nonfree-source repository Enabling rpmfusion-free-updates-source repository Enabling fedora-source repository Enabling rpmfusion-free-source repository Enabling rpmfusion-nonfree-updates-source repository Cannot find a valid baseurl for repo: rpmfusion-free-updates-source/20/x86_64 Am I doing something wrong? Or is it something on the repository side that isn't ready yet?
