GOG used to have a small selection of DRM-free movies that you could buy to download and that would then make all those things possible to do in a way that would be legal or at least able to do locally in a way that would have a zero risk of being discovered even if it violated some EULA. Announcement from 2014:

Sadly http://www.gog.com/movies now redirects to http://www.gog.com/games and the movies link that used to be on the front page is gone. Based on a comment in that announcement thread it looks like the movies were silently removed already back in 2023. I only noticed it now. They never seemed to really add any new movies and the existing ones were mostly game-related documentaries.
