wow. I never new there was a max devices per account. I was actually at the limit before I discontinued two series 2 tivos. My solution for extra feeds (not knowing I need one) was splitting one hdmi feed (it is to a patio monitor and uses the same AV receiver so having the two feeds controlled by one room was never an issue) and having two small comcast digital signal devices on TVs in the two infrequently used rooms. That really is a waste of money but it is not too much more on the cable bill. Realistically, the best solution would be a streaming media server to serve the majority/all of the rooms It can be a combined with tivo solution and determine exactly how many TVs need live tv or a cord cutting solution. My guess is the kids tvs could all go streaming (non-live) tv. Watching habits of younger generations have definitely changed. Just get a large storage media server (you can get a damn good machine for the price of 2 bolts and 10 minis), a switch, run ethernet, and pick your favorite streaming device(s) (fire, roku, chromecast, apple, etc). It is almost guaranteed to be cheaper and have pluses like shared music as well.
