Screen capture does not work with DVD player
I had a DVD created of old family movies. Now I'm trying to capture a image using the screen capture tools but all I get is a gray image. I've tried shift-command-3-click, shift-command-4-click, Grab, etc., but no luck. Here is what I come up with:
Although the DVD player is playing the file, no files are showing up when I open the DVD disc. I have a MAC PRO with El Capitan. Thanks
