Record screen without getting detected i.e. blocked and blacklisted

[Jammy2020]

Hey guys! First post here!

tldr: I want to record my laptop screen while I stream a video that I have paid for. Can they detect me recording the screen?


LEGALITY:

I know this could be deemed unethical but I will NOT be selling or distributing these videos. I just want a copy for myself. Also, recent laws about time-shifting media mean this is NOT illegal. To those screaming piracy - if these were movies one could easily wait for someone to torrent it. These are education lectures I have purchased and can stream.


THE SITUATION:

My subscription allows me to stream unlimited videos. These are educational videos so NO netflix, movies etc. I will be watching these tutorials again and again. I just want a copy for myself that I can actually use the content I've paid for!

The subscription is damn expensive and I have to watch the videos a number of times. I could probably go through everything once in 8 weeks and get myself a copy of all the stuff. If I keep subscribing till I'm done with them (repeat viewings) I'd probably end up subscribing for 6-8 months and I don't want to do that.

Often I want to watch/get time to watch the videos when I have no internet i.e. on my commute etc. I want to 'make a copy' of the videos so can have them on my tablet/phone BUT the company provides no links and also says any attempts to download material and you get blocked. I don't want to get blocked.



MY PLAN OF ACTION:

Very likely any attempt made to intercept the stream and record it directly can be detected. Not going to do this. Also, don't know how to.

So I'm thinking I will play the video and record my desktop i.e. a recording of whatever is happening on my screen = the video
I have done this in the past and the quality if good enough for my purpose.

This is time-consuming, but it does give me a copy of the video in a decent useable quality = fit for my purpose.



MY QUESTION:

CAN THE COMPANY DETECT me recording MY screen? If they can I get blocked and blacklisted.

This is not some huge company like netflix etc. but definitely not some mom-and-pop operation either. But definitely they have a high-standard of technology.

If there is indeed some way/technology for them to detect me recording my desktop - how expensive is it i.e. how likely is the technology to be used to catch people doing this?

If this is not feasible - what else can I do?

If all else fails, I could just connect my laptop to the big screen and record it with a camera. Not very keen on that. Too much effort + the flicker etc.


Thanks!
