l717hz | How come taking screenshots of video was difficult back in the day? | In the 2000s I remember when I had video players playing a file, trying to take a screen grab of it made a "hole" where the video was. It was pretty nuts, when I pasted the screenshot into Photoshop the hole showed areas of my video player application itself behind it.
