I agree. When I go to http://www.hbogo.com/activate/ and then select Android TV, Comcast/Xfinity is missing from the list of "supported providers." All the other major cable providers are in the list. And Xfinity is in the list for other platforms like Amazon Fire.
It seems Xfinity just needs to call HBO and get themselves added to the Android TV list. Attention Xfinity staff: please do that ASAP. Thanks.
this is not a technical problem but a market failure problem. if you want that accees, you, me, and everyone else staring at useless android apps on brand new systems, need to pick up the phone and call comcast to demand that they allow these services through. My bill is 280/mo. That should be enough to get me the access I want to conent I've paid for. Pick the phone and call call call.
