A video or DVD must be playing or paused for the
Full Screen command to be available. To return to full mode, press ESC.
When you switch to full screen, the Player
controls may appear for a short period of time (depending on the
capabilities of your video card and the functionality of the video
or DVD that you may be viewing). To restore the controls after they
disappear, move the mouse or press any key. To prevent the
full-screen controls from disappearing, click the Always show
full-screen controls button .
