Oh, I just remembered something. I have a client that switched out some of his cable boxes for Rokus. Due to some law that was passed making cable companies have to provide another option than renting boxes, Roku now has a Time Warner app. As long as he subscribes to time warner for tv service, he can add as many rokus to his house as he wants and use those instead. I don't know if they have a Comcast app, but you might check.
