I am a somewhat technology challenged senior citizen trying to save expenses by cutting my cable tv. I have an extremely dumb question. I managed to download the software onto my PC (Windows 8.1) but I just don't understand how it connects to my TV. Do I need a smart TV or do I have to connect the devices with an ethernet cord? I can't believe that is the case, but I would really appreciate it if someone could explain this procedure. Thanks in advance.
