I will admit I haven't tried this, so I don't know if there's some encryption that would be problematic but there are definitely HDMI video capture devices that are very reasonably priced and would let you record content. BUt most all content is online so it seems there would be very little demand for the feature you are talking about. I can just go to my friends house and log in to whatever app and watch the same stuff I can at my house, or use something like a Chromecast.
