I think there are some strange interactions between xscreensaver,
xfce4-power-manager and vlc. I like my monitor to turn off at night, and
I've found that I have to go into the power manager settings and change
the time before the display shuts off, or else it won't turn off. A change
of one minute in either direction is sufficient.

There's also a button on my panel that runs 'pkill vlc' for the times when
vlc doesn't really go away after closing it.

I don't know the right answer.

-fsr
