But you can't watch HBO Go on your DirecTV receiver, it's not a channel offered. The only way you can get HBO Go anywhere is to be an HBO subscriber to begin with. D* just chooses to not authenticate that you do already subscribe to HBO if you're trying to use a Roku device. They gladly authenticate your subscription so you can watch HBO Go on your pc, your laptop, your phone, iPad....... So far their official (maybe) stance is that they'd rather you watch their HBO VOD offering, which is a freebie that you get on your DVR if you already subscribe to HBO...... They are trying to compete with one of their own content providers, which IMO is idiotic.
