I am trying to use OBS to screen record a movie I purchased on Amazon since it apparently doesn't allow you to download the movie for use on other devices. I've tried Display and Browser source options both as well as mkv and mp4 output but I get the same thing, audio but black screen for video. Does Amazon have some kind of recording protection built in? OBS works normally otherwise as I've tested it. I've also switched GPU to power save. Any help is appreciated
