I don't think HBOGo requires any relationship with ISPs HBOGo certainly requires a subscription to their traditional channel, but I don't think there are any deals required with your ISP. I used HBOGo without trouble until I dropped Dish and thus my HBO subscription recently, and my ISP most definitely has no deal with HBO. The HBOGo website only makes mention of participating TV providers, no references I see to any requirement for your ISP.

Yeah, that line sounded funny to me. I stream HBOGo on my Rokus over Comcast HSI. My HBO sub is from Dish.
