[CentOS] CD-Mount on CentOS-6.7

When I load a blank cd into the optical drive on my CentOS-6.7
workstation I am not getting any window or visible mount action on my
Gnome desktop.  Formerly, when I mounted a writeable media in this
drive on this host I would see a nautilus style file browser window
open with inducements to add files.

When I visit /mnt I see nothing:

ll /mnt
  total 0

My fstab does not seem to have much to say either:

cat /etc/fstab

The hardware seems to be there:

Now, I have not played with any of this stuff in quite some time and I
used it late last year to cut CentOS-7 ISOs.  So my question is: What
has changed to cause this behaviour?  Any ideas?
