It’s not just the quality of the video, streaming doesn’t come with any bonus material, commentaries, and ownership. That’s part of what I meant about superiority. Of course, with Netflix you don’t really have the ownership part, but I’m still not quite happy with the internet tether and variabilities in quality streaming has.
I had read Netflix’s DVD service is still profitable, and have further read from various other sources that they have no plans to end it, but of course this may change down the road. It still has a user base of around 5 million people, and they keep refining their centers to help reduce costs, so ending it doesn’t seem to be in the cards.
