Image Alt Text: "After downloading a 2.5GB movie
Me: Presses play Movie unsupported file" A person is shown with eyes on her laptop punching the wall beside her, causing it to crack.
Happened to me a few months ago. Had a ticket for our District Attorney office, trying to playback a security camera footage from a parking lot or something. It would open, but, the person that was supposed to be seen would show up for a few frames and glitch out.
Turns out the cam system it came from uses some very proprietary codec. So the footage was effectively useless without their special sauce player/codec
