[Launchpad Bug Tracker]

After upgrading several systems from 15.04 to 15.10, none of the systems
were able to recognize the DVDRW in userland. This was tested with two
different USB DVDRW's

*-cdrom

This was also tested on 4 different systems. Three with Ubuntu and one
with Kubuntu. I upgraded Kubuntu to 16.04. The difference in 16.04 is
peculiar. The DVD player does not appear in any file manager. However, I
could access the DVD via VLC. Attempting to play the DVD failed however.
There was no sound and any option  chosen on the DVD menu resulted in a
blank/black screen.

This bug seems to afflict other users:

I've also included this report here:

But am filing a new bug since the other seems to be dead and/or
outdated.
