How Do Filesharing Scene People get clean copies..

How do the filesharing/scene producers/rippers create pristine videos without
the litter of graphic boxes i.e. Skip Intro; Skip Recap; Skip Ending Credits; Next Episode... el.al.
that one gets on streaming platforms i.e.. Netflix, Hulu, Amazon Prime Video, Paramount*, etc.

When I tried to record content using my roku box into my pc's Hauppauge Capture card or a tivo
I can't get a clean result like these folk - just the litter.

So how does it get accomplished?

They use private exploits to decrypt the video and audio streams, effectively cracking the DRM these services use. Screen capturing is actually the last resort of streaming piracy - even a "perfect" capture will add some loss in comparison to the original.
