If Iceberg says something, you could bet your pay check on it.
But if you are getting wet and Dish says it's raining, you should still look up and see.

But they're still learning and getting better.
What you want to do is on Page 11:

Just ignore the 3rd satellite signal, and use a DPP44 instead of the DP34.
Per Page 4 and 5, you must connect either Ports 1 & 2; or Ports 3 and 4, to the DPP44. However, I believe I have read where someone said they had a problem using one pair instead of the other; but according to the manual, either pair will work, you just cannot use one cable from each pair when going to a switch.
As Iceberg said, with the DP Quad and the DPP44, you can feed upto 6 receivers.
After feeding the DPP44, the DP Quad can feed either 2 single or 1 dual tuner receivers.
Then the DPP44 can feed 4 receivers; either single tuners, or dual tuners with a DPP Separator.
Edit: I don't think this will be an issue for you, but I believe the distance from the Dish to the DPP44, plus the DPP44 to the 625, can not be more than 200 feet total.
