So I currently have DirecTV right now and for those of you who aren't familiar with that setup it's one coax from the dish to a SWiM (big splitter) which then splits the signal to each individual box. DVRs still only require 1 coax. I'm interested in the Joey/Hopper configuration. I will be setting up 4 HDTVs (and a 5th one with an HDMI splitter) and only need one DVR, but since the hoppers only have 3 tuners does that mean I'll need two hoppers? Can one hopper share recorded shows with another?
