Yup. The "do not copy" thing you're talking about is known as HDCP. It'll likely get in your way. There are devices that'll strip that out of the signal path but, they're kinda' spendy.

Putting aside the obvious illegality of recording copyrighted material,

You can purchase a "4K HDMI" capture card for around $35. It will only
record 2-channel stereo sound, but does the HDMI standard included a "do
not copy" signal or something that would prevent recording the stream?___________________________________________________________________________
