Amazon Prime, like many services, is a DRM hell. It won’t go to over 480p on Firefox on Linux at my end. However, instead of a rant, I am interested in why this is happening. Say, I rented the same film from YouTube Movies(Yes, such a service exists) and the quality can toggle all the upto 1080p but the same title on Prime Video is stuck at 480p. Is it because both services use two DIFFERENT kinds of DRM?
One of the reasons but not the main one I cancelled Netflix (to be honest I just thought the originals were bad and any I actually gave a a chance they cancelled almost immediately).
But yeah their selling thing like 4k at a premium and making it almost impossible to ever actually use it. Better off just pirating.
