Multi Reciver install help

[dnero]

I Just had the new VIP 722 HD Dish network receiver installed. I had the 721 501 and 508 receivers the installer hooked this up with a DPP44 switch but told me I would have to buy a second DPP44 to hook up my older dual tuner 721 as the splitter did not work. My 110/119 dish has a quad LNB he used two cables off this dish to feed the switch plus one from the 61.5 dish. This left two cables unused off the quad LNB if i hook my 721 up to 110/119 dish to the two unused cables will this give me problems as far as switching and channel polarity with the other receivers?
Any help is greatly apreciated.

The Easiest way to install all these boxes is:

Use 1 dish 1000.2 with 3 cables into the 1st 44 switch.
Use the ex 61.5 dish and run the line into port 4 on the 44 switch.
You will need a 2nd 44 switch for the 5th box.
It would be the cleanest and easiest way for this install.

As your 722 box is mpg4, you will need the 129 sat.
61.5, 110,119 and 129.

Hope this helps
