How many times have you wanted to take a screenshot in the DVD Player and couldn’t.  Apple has put restrictionsin the operating system to prevent this, for copyright reasons.  However using the following commands it instructes the OS to ignore the imposed restrictions.

1) Put your DVD in your computer and open DVD Player (Applications -> DVD Player) if it does not open automatically. Go to Video -> Maximum Size, or hit Command-3. Fast forward to the frame you want to capture, or select the scene to start at.

2) Open the Terminal (Applications -> Utilities -> Terminal). Type this, or copy / paste it right in the Terminal:

screencapture -i ~/Desktop/dvd.png

Your mouse should turn into crosshairs. Now hit the space bar. Your mouse should now be a camera. Click the window the DVD is playing in. A file called “dvd.png” will appear on your desktop.
