So is the service download and play or streaming? By all actions, it's both. You select a program and it offers download options and then says it's downloading and later you get a pop up that tells you it's done. And when you watch it there is the "Stream Quality Dots" that, I guess, somehow register your connection speed while "streaming" and PQ reacts to the level of dots. So is it downloading for play or streaming? Lately while watching my picture drops (goes black) or looses resolution or get good, audio stays on, and the "Stream Quality Dots" change.

Then that would be streaming? Because if it were downloaded, there wouldn't be that kind of dropout and no need for the SQ dots.
