Buy movies or shows you like on Blu Ray, and use Plex. It takes a few years to break even, but by that point you have hundreds of movies and shows you like. This really only falls down if you want to watch a show within a year of the season ending.

Discovery is good, works on every platform, offline sync with transcoding so you can decide how much space it takes up, hdhomerun for dvr-ing live OTA sports, camera backup on vacation in full resolution. It's amazing if you're a little patient on the ramp-up.
