re: Cox is making me order their box to use HBOGo

You need the box to decrypt the HBO signal if you have it at home. And you need it at home before you can log in at HBOGo. You can't just get the channel and expect your TV to decrypt it. You COULD buy your own cable box, or get a cable card, but I'm not sure of how to go about it or how that would work with Cox.
