Trying to comprehend this the most simplest way!!! So I buy a Slingbox, plug it into my cable box at home (on a tv not used while we are away). Now I want to watch tv from home while on the island. It is NOT a smart Tv. I plug a Firestick, Roku, or Apple TV into the TV and get it hooked to the internet. Do I then go to an app or open the browser and sign into my slingbox??? Then control it with the remote from what ever streaming device I am using???
