Get the DVR if you think you'll use it, I have 4 around the house, 8 tuners. Can't recall using more than 5 at once, Sunday night may give it a workout. The Geni is nice, 6 tuners and optional boxes fed from it at other TVs.
I think I've been with them for 14 years and never an issue. I opted to do my own installs because I'm picky, but know others that got D installed and they were happy with the work. There are possible ways around the sports issue, just depends on if that is an issue for you, your location may let you get what ,if any, you want.
