I didn't see through to the end because Rossman was making the same point over and over and over and over. But what he didn't talk about is that Netflix specifically does not provide the highest tier of quality to PCs. That's to prevent piracy of super high quality streams. The blockage is very much intentional and not without cause. Similarly, Netflix often does not play well with a whole host of Android streaming devices over which they have no control of the stream for exactly the same reason.
I agree with him otherwise, I just wish he'd have gone into those reasons. Your super fast gaming rig being 'not compatible' has nothing to do with its impressive hardware specs.
