For my daughters gymnastics gym, I've successfully setup an old Tivo (analog), with a video camera source (HDMI) to an HDMI capable TV. As you know, my picture is limited to analog because of the older Tivo that doesn't support HDMI in. So, now it's 2017, is there any replacement for my old analog TiVo system that will accept HDMI as an input? Thanks for your thoughts. I'm after the instant video delayed replay playback, that's what works for our gym.
