You can also record the HDMI signal, which HDCP is supposed to guard against. But it was cracked even before it was being used/enforced. So now it only serves to create incompatibility issues and bugs for paying users. Even though it has been irrelevant for more than a decade.
I guess the reason for why it still exist is because it prevents/hinders legal products to circumvent it, since that is against the law in many jurisdictions.
Anyway, the downside of both solutions is that you have to re-encode the video, which will never be as good as the original source you get directly from streaming it. Though I'd imagine the difference is quite negligible. More effort though!
Hey that's me! Every time I open a website that has DRM to the max like Spotify or Netflix, my second monitor goes black for like 10 seconds. Fun times.
I just restart the AppleTV and everything works again. I don't know what causes it, but it's been going on for at least five years across multiple AppleTVs, two televisions (Samsung and LG), and OS updates. But it persists, just like the AppleTV bug that kills all audio if I turn off the TV without turning off the AppleTV first. Again, the solution is to restart the AppleTV.
