I will be moving into a house and want Live Tv and ability to watch recordings off my Elite in at least four other rooms. The rooms have coax. I have Comcast Cable. Looked at stream - Don't like because of ios only, video quality, and no hdmi out. Looked at mini - Don't like because it ties up Elite tuner and needs subscription. Can I do this with additional cable card Tivo's but no added subscriptions? What can a cable card Tivo do (or not do) without a subscription? Which cable card Tivo model(s) can I use?
