Oops, I forgot that mounting a video DVD is possible, just mounting an
audio CD is impossible, but it can be played.

Did you try mounting by command line?

Audio CD:
=========

[rocketmouse at archlinux ~]$ sudo mkdir -p /media/optical 
[rocketmouse at archlinux ~]$ ls -hAl /media/optical/
total 0
[rocketmouse at archlinux ~]$ sudo mount -t auto /dev/cdrom /media/optical 
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.


Video DVD:
==========

[rocketmouse at archlinux ~]$ sudo mount -t auto /dev/cdrom /media/optical 
mount: /dev/sr0 is write-protected, mounting read-only
[rocketmouse at archlinux ~]$ ls -hAl /media/optical/*/
