That was for an old version of HDCP up to 1080p, right ? Not to mention, capping and transcoding is tedious and will alter the quality. I doubt if anyone still does it as there seem to be better exploits for the determined.

There are splitters that can do 4K 60Hz HDCP 2.2. You have to really search for them because AliExpress will remove listings that mention this feature explicitly.

Due to the amount of very high quality files you have on torrenting sites, L1 is being broken already indeed, they just don't publish the methods and devices they are using for that so they don't get patched.

Yes, all the files you see on torrent sites are decrypted using L1 keys extracted from a nvidia shield using a TrustZone exploit.

Well not exactly, it's hard to patch this when the keys leak from a very popular device.

Most AV Receivers have a "downgrade HDCP" feature where they get a HDCP 2.2 input and produce an HDCP 1.4 output.

Recording e.g., a 4K HDR movie off Disney+ is absolutely trivial this way.
