Is it possible to get HBO on my Mac mini that is connect to an LG TV by HDMI? I only have internet service from Xfinity; I do not have any of their TV packages. I really would rather not use my iPad or iPhone, unless I can somehow get it to the 46" LG TV. It seems like this would be easy information to locate, but I am struggling to find information on it. When I visit hbonow.com it says I have to download an app to my iPhone or iPad.
