If you’ve got Comcast and a Roku, you might know the pain I’m about to describe. You find HBO GO via the Roku channel list, start to set it up, and suddenly — bam! If Comcast is your cable provider, that’s where it ended. You could find HBO programs via On Demand or the app, but that wasn’t quite as handy as your Roku. Those days are over. Comcast has announced they will be supporting Roku for HBO GO and SHOWTIME ANYTIME.
