I have seen conflicting answers (on Amazon) about whether you can record anything other than OTA channels. Ideally we would like to be able to select from the guide, both OTA and live subscribed cable channels to record for later viewing. I see that the HULU app is supported. Is HULU Live TV? We're just trying to schedule recording, for example, live broadcasts of a show from HGTV. Am I wrong or is Air TV is the only product currently offering this functionality.
