We are thinking about getting this Roku player or Amazon fire TV, but to get all of the channels do you have to be members of all of those channels? For instance I have memberships for netflix, and hulu, but do i have to be a member of HBO Go , etc.?? This streaming stuff is all very confusing. We are trying to stream on 3 maybe 4 televisions. My dad is worried about not being able to watch football if we stream?
