Thank you pclin for reply
I had just researched it in Google about DRM and I found solution here:
How can i remove The DRM on Hbo Max
I've been trying to do Web Dls of episodes of show in Hbo Max is there a way to do a proper Web DL
www.reddit.com
It's look like, I must download software (example audials) or download python script 'that makes downloading the encrypted streams, decrypting and muxing easier'. It's not for me
I would like have add-ons for chrome or something, where I can watch movie online with working hyperion.
I didn't see the solution.
I'm slowly starting to doubt whether it will be possible to solve it in this way and probably I will must to buy raspberry pi and grabber
