After performing a Workstation install, I wanted epiphany, so I started r-c-packages and selected to install it. It prompted me for CD #2. I inserted it, and clicked OK. It said it couldn't access it. I tried mounting the CD manually and then pressing OK again. That didn't work. I was able to manually install the RPM from the command line from the same CD.
looks like a duplicate of bug #105767
