How come I can only use two TVs in my house?
it's not clear what you are asking. if you have set top boxes in your home then you can stream on up to 5 devices at the same time. if you have no-set top boxes in the home (instant TV) then your limit is two streaming devices active at any one time.
Are there any plans to expand the two-stream limit? I'd like the five you can get with a X1 STB. And don't tell me to get an X1 STB as a solution!
nothing planned nor announced.
