This problem occurs with 2 machines (laptop) on which I installed fedora
23. Problem does not occur on a third computer running fedora 21. On one
of the laptops where previously installed a debian, and no problem occured.
It is not a vlc problem; vlc mounts and reads these dvd without any
problem, I think that it is an xfce problem, but on my fedora 21 I have
the same version of xfce as on laptops with fedora 23.
Is libdvdcss (not a fedora package) installed on your working systems?
