[PlanetCCRMA] intallation problem on Fedora Core 5

[sam kni]

When i try to run "apt-get install
planetccrma-audiovideoapps" i get the following
result:
 
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package planetccrma-audiovideoapps

I'm guessing that the problem is that i don't have the
Planet CCRMA repository in /etc/apt/sources.list, but
i have no idea where to get these for Fedora Core 5.
They are listed in the installation instructions for
Fedora Core 4, but not for 5. 

Some information that might help:
I'm running the command as "su -".
I had to install apt just before running this command
as i wasn't on my system prior. 

I would very much appreciate any help you could share
with this very excited beginner. Thanks in advance.
