A:Answer If you connect this device to a computer, and if that computer has an HDMI port to connect to an HDTV, then you can play on this device, using your computer, connected with that kind of TV. If you have a special adapter which can connect your Cable Signal after being decodified for your TV, maybe you can record the decodifief signal with an specific software, and if you are able to do that, which I cannot guarantee, then you can also save your recorded signal on Disc to watch the videos again for personal use, like people did time ago with Video Player/Recorders. I suggest you ask Best Buy Geek Squad either by email, chat or phone to tell you if you can do any of this things, and if they recommend you any software and adapters.
