While watching the This Old House channel on the Roku channel it will randomly stop and go back to the Roku channel home screen.
crash.
problem with channel or your roku is too old.
i would do a system restart.
that frees up the memory,which may make a channel work smoothly.
I dont know about the Roku being too old. We had a Roku Express and we were having the same problem with it randomly going back to the Home screen. After chatting with Support on the Roku website and they were unable to fix the problem, we went and bought a Firestick... that solved our problem.
