Installed Fedora C4 fine, setup webserver, etc. Works great. Attempted to install some other applications. system asked for install disk 4, but can't read it. I attemped to read other disks with the same result. If I run autorun, I can see the files on the cd and browse, but still can't install new apps. Hardware is fine.

"Can't read cd" is quite unclear. Are you able to mount it? Did you have any error message? Even when you type "dmesg"? If the mount succeed, is there something else wrong?

If I run autorun, I can see the files
What autorun? Do you mean on windoze? There is no autorun that I know on linux... unless you mean you boot from cd??

I can see the files on the cd and browse, but still can't install new apps.
Can't install new apps? Yes? Any error messages? What are you trying to use to "install new apps" ? Yum? Rpm? Automated tools? Boot-from-cd-add-things-during-install? Copy-paste?

In any cases :
- Can you mount the cd?
- Can you read the cd? (using "ls" or whatever the cutty GUI apps)
- What are you trying to install and using what?
