I have done some basic research into this before and it seems to be a bit of a trade secret among release groups. They don't heavily advertise how they're doing it to limit what the streaming services can do about it.

this is your new bible https://cdm-project.com/explore/repos you will find:

• guides
• tools
• a discord community about this topic

Is there something in there you want? Why don't you just sit and enjoy getting most of their content from torrent? For the best of everybody I prefer the methods are not widespread so release groups can keep doing their job.

There's the way of using non-HDCP-compliant HDMI splitters to screengrab the content, but I think some groups have found a way to decrypt the content of streaming sites directly.

Your best chance would be to use a video capturer and record. However, scene groups actually download the video from the servers. ¿How? Probably they found an exploit and developed a tool around it but certainly it's private otherwise the exploit might get fixed.

Well first you need a Netflix and Amazon Prime account.

I think they screen record it, but not through software.

Maybe they use a hardware to do that.

Damn, I wanted to ask this same question but apparently it is pretty impossible if you are not a experienced pirate. sadge

If this is just for the fun of it I would try to run these services inside a virtual machine and just screen capture them. Never tried it but I don't see a reason why it won't work.
