So I've been experimenting with channels through Amazon Prime. You can access and download content from Britbox if you go through the Amazon portal. The only thing to watch for is to check the content that is offered. Just because there is a portal through Amazon doesn't mean that all content on the channel is available. CBS All Access has an Amazon portal but they do not offer ALL of their content through the portal. Series like "The Love Boat" only has partial seasons through Amazon but all episodes are available directly from CBS. If you work the 7 day free trials that's still a lot of content we don't have available right now. Use it for what its worth.
