There’s a documentary that’s more than a decade old that now only exists on Amazon Prime. I have searched everywhere for this but the website (and thus DVDs being sold) doesn’t exist any more, there are no torrents, no second hand DVDs for sale that I can find online… I’m OK with buying the doco from Amazon (albeit not happy about giving Amazon any money) but once I’ve bought it I don’t want to be locked into Amazon’s infrastructure (I do not trust streaming services to keep such niche videos available indefinitely).

So how would I go about downloading and removing DRM from Amazon videos?

I read an old post about mp4decryptgui but that hasn’t been updated in 3 years so I don’t know if it works any more.

The only other methods I’ve found involve buying expensive Windows only software (I’m on Linux but can dual boot if absolutely needed).

Thanks!
