FYI, blu-ray discs include executable code to, among other things, update the banlist of encryption keys on your player when you try to play a new movie. Even if you never plug your player in, there's still the very real possibility that putting in a new disc will update your player such that your old discs no longer work due to a key revocation.

Do you know if UHD implemented something similar? Its not the same tech, though doesn't mean they couldn't have added it.

If it is at that point, then the only solution is VHS and rips, short of preventing revocation within a bluray player
