I'm a physical media collector by nature and habit but I do have iTunes with a couple of movies and TV shows on it. What I like about iTunes is its very easy. I click 'Purchase' and it downloads. I can see the downloaded file on my hard drive so it's mine and I can make a backup. I thought I'd give Amazon Prime videos a go. Not a monthly or yearly subscription or anything. I simply purchased one episode of a cartoon series to watch on my PC. All I can seem to do is stream it. No option to download the episode. Is this how it is with Amazon Prime Video?? Why can't I download this episode onto my PC for safe keeping and off-line viewing? Thanks.
