I remember that in the windows 9x age I tried taking screenshots of the matrix avi and all I got was a black rectangle. I assumed that it was how the graphics worked as when pasted in paint it would act like a “hole” where if you moved the window it stayed in the place of the video player. Like if it’s not in the graphic buffer because it’s an accelerated directx video or something like that. Not an expert and also more than 20 years passed and my memory is wonky
That’s precisely how the old ATI TV tuner cards worked. They masked part of your display and any pixels that were the mask color became the video player, because the decoding and injection into your video signal was happening in hardware on the tuner card, not on your regular graphics card.
This allowed you to do dumb stunts like scribble hot magenta areas anywhere on your screen with MS Paint and the scribbled areas would magically become video from the TV tuner.
