So technically it sounds like he was getting 2k screenshots, which apparently was fine for what he was going for. There have been in the past devices that have removed HDCP on 1080p content, that could be picked up off Amazon/Aliexpress for like US$20-$30. Sure the bitrate for raw HDMI content isn't something you'd want to store raw, but if you're willing to recompress it, you can have something manageable, while still getting 99% of the quality of the original. I haven't seen anything yet that will strip 4k HDCP yet. (Maybe the HDFury? But that seems like a lot of money when you could just have a netflix subscription)
