Title:
  16.04 some dvd do not mount automatically (but do in 14.04)

Status in util-linux package in Ubuntu:

Bug description:
  Hi,

  here is a dvd. And ubuntu 16.04.

  When I insert that dvd, it does not show anywhere, neither in launcher
  nor in nautilus.

  But I'm able to read that dvd using vlc through menu media / open a
  disc.

  I can manually mount that dvd with

  sudo mount -t iso9660 -o ro /dev/sr0 ~/Bureau/dvd/

  Once mounted there's a dvd icon in launcher and it appears also in
  nautilus left panel.

  That same dvd automatically mounts when running ubuntu 14.04 on the
  same computer.

  I have also tested other dvd's on ubuntu 16.04 and *most* of them show
  / mount as expected.

  But *all* of them automatically show / mount in ubuntu 14.04.
