In the GNOME Disk Utility, the disks show up as X.X GB Unknown, and will not mount. I have to manually go into a terminal, type sudo mount /dev/sr0 /mnt and just deal with it. This is a real pain, and I just recently figured out why. According to this: http://superuser.com/questions/730130/how-to-get-ubuntu-12-04-to- recognize-the-udf-filesystem in addition to this: http://www.linuxquestions.org/questions/linux-desktop-74/some-udf- dvds-will-not-mount-unknown-filesystem-4175550577/ I deduced that the kernel was not compiled with UDF support.
