This is really unfortunate; when Netflix launched streaming, they had a partnership with Start that had a lot of popular movies, but now you would need to mix and match two or three services to get similar coverage. I've been buying more and more discs lately, because I want to watch something today, and at any time in the future.
I hope, one day, we get compulsory licensing for movies and TV shows, like is available for music -- then we can really watch whatever, as long as it has been digitized.
Appears that will never happen.
