Have a Shield TV, just thought I'd sideload the latest HBO Go APK because I had Xfinity, and Android TV isn't supported on the official HBO Go app.
I could log-in no problem on the mobile app, but what surprised me was that it bitstreams DD5.1+ content. Definitely is HD. As usual you need a mouse to navigate, but it works.
Cool! Also, fuck Comcast. This is precisely why I switched to HBO Now.
