Relevant but not Amazon Prime - I looked everywhere for somewhere I could legally download Star Wars in HD to watch on a plane. But since my Surface Book apparently doesn&#x27;t support HDCP, I couldn&#x27;t. The best I could do was SD from the iTunes store. Eventually, I just paid the $20 somewhere, then torrented it in HD. It doesn&#x27;t seem like the kind of thing that should be completely impossible in 2016.<p>I see that Amazon Prime offline is only supported for Android and iOS, and I bet spotty HDCP support on laptops is part of that.
