This is the restriction on this app.So this APP is only good in a home with STANDARD CABLE(at least here in NW PA. May be different in other TWC areas), a modem/router registered with TWC. That is it.This APP just provides the convenience of being able to use the ROKU, or other device, for TV in a room where CableTV may not be accesible, or you just do not want it all the time.
