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....
