For tv and movies you're basically hoping they had a DVD release. All the options options to "buy" are essentially one time fees to stream it on various services or when you get a download it will have HDCP drm on it. I can understand why they don't offer drm free versions because I would give them away like candy to my friends but it's mostly all available pirating anyway so I doubt it really matters.
I don't know why you're downvoted? If you want to stay legal, you gotta buy DVDs and Blu Rays, mostly used or in bargain bins to keep it relatively affordable.
