Good(-ish). The optical device is there but it's an old combo CD/DVD-ROM drive.

But, this is promising (BTW, my prev ide-cd thingy was left over from another CentOS box. It's not effective on this one.).

I popped a CentOS DVD in, got one image on the desktop and one mount listed from the mount command and one nautilus box popped up..
I removed that and inserted a Mark Knopfler DVD and totem automatically popped up to do it's usual bitch about plugins.
Mount showed one on /media/SHANGRILA and desktop had one ICON for it.
So what does grep ^hda /var/log/dmesg tell you about your optical drive Bill?
Being a Unix user of 25 years, I'm always a little suspicious of these new-fangled things like desktops. ;-) However, if you're using Gnome then please have a look at System --> Preferences --> Removable Drives and Media I know that there is a difference in the automount of a data CD/DVD when the user is root (basically it doesn't, you would have to right-click on the icon and select mount manually) and when the user is a normal user (automount err automounts).
Lanny or Bill - Sorry I'm loosing track. One of you has three boxes; in boxes #1 & #2 the drives behaves as you want, in box #3 the drive misbehaves. Have you tried the test of swapping the drives in - say - boxes #2 & #3 and seeing if the problem moves with the optical drive or stays with box, #3?
The hd{a|b|c|d}=ide-cd kludge certainly isn't required with the CentOS 5 2.6.18-series kernels. I last came across it with a 2.4.8-* IIRC.
Just a few more of my thoughts, for now.
Alan.
