You confuse the medium with the means of distributing said medium. The stream (distribution) is the DRM preventing me from doing what I want with the movie (medium). In other words, the stream itself is the DRM, not the thing that is restricted.
I disagree. What Netflix "Watch It Now" promises for your $8/month is the ability to stream a movie to a supported device. The stream is the product and the delivery method. DRM makes it practical, yet I don't think DRM restricts you from doing anything you should be able to do with that stream.
