I need help in determining what equipment I will need upgrading from one 722 and one 622 to a hopper2 system. My 722 is in the "cave" and feeds TV1(HD) there and feeds TV2(SD) in the living room. The 622 is in the basement and feeds TV3 there and TV's 4&5(SD) in the kitchen(main floor) and master BR upstairs. Controlling the 622 will control both TV4&5(same show, etc). The cable to TV4 ends at TV4. The cable to TV5 ends at TV5. I am assuming there must be a spiller somewhere between the 622 and TV's 4&5 that must be in a wall somewhere but I don't know where. What equipment would I need to control each of all 5 TVs (all HD) with the least cost? Thanks
