MP3 to CD

I have an MP3 that I want to put on CD. K3B has a plug-in to do this called k3b-mp3, but it’s not in the standard distribution for Fedora 8. A poster said it’s available from the Livna Repository. I download the repository RPM only to find out I already had it installed. Now I wonder why it’s not showing up in the package manager. Browse RPM Find to look at package contents and see that k3b-mp3 is in the k3b-extras-nonfree package. Installing this package will also install K3B if it’s not already there.
