I have yet to get a DVD to read in CentOS 5. I can install from DVD and then reboot and then the DVD drive is no longer accessible. It works with several live CD and DVD images with no problems however. This is on an HP system. I think it is an OS problem.
I will test in some other systems and let you know my results.

Here's the FC6 Install DVD I want to install an RPM from:
[root@dell1602 ~]# dir /mnt/cdrom eula.txt RELEASE-NOTES-en_US.html RPM-GPG-KEY-fedora-rawhide Fedora repodata RPM-GPG-KEY-fedora-test fedora.css RPM-GPG-KEY RPM-GPG-KEY-rawhide GPL RPM-GPG-KEY-beta stylesheet-images images RPM-GPG-KEY-fedora TRANS.TBL isolinux RPM-GPG-KEY-fedora-extras README-Accessibility RPM-GPG-KEY-fedora-legacy [root@dell1602 ~]#
The contents of the DVD still do not show up if I open the Icon for it on the GNOME Desktop or if I click on "Computer" and then open that drive. Doing that, the media still appears to be empty.
Like you, I am now 99.9% sure that this is not a HW problem. I am very puzzled, why this works, without any problems, on 2 of the 3 boxes I did clean installs on, last Thanksgiving weekend and not on this box. Lanny

I am unclear on which parts of the above post are yours and which are from the thread.
However:
Can you access the contents of the DVD from a command line at all? If so, have you tried doing the rpm install from the command line?
What make and model of DVD drive is it? What kind of controller is it connected to? Have you checked all the cables to make sure that they are properly connected and the drive has its jumpers in the right place?
I have heard that mixing FC and CentOS rpms is not a good idea, although IIRC FC6 and CentOS 5 are reasonably close.
Just wondering....
