There's something like Plex, but for rich people and with DRM.
You buy some kind of stupid expensive home theater appliance that's basically just a NAS, and it downloads movie releases that the company licenses. I think it was a subscription service that includes basically all theatrical releases you might want to watch, even before blu-ray releases are out.
