The only way to have 5 orbital locations is to use a DP21 per tuner. In your case it gets a little difficult because you have 2 dual tuners. So in your case you'll need 2 DP21s per 622 but since the dish pointing at 61.5 will only have two outputs (dual DP lnb), the installer may use a couple of satellite splitters to split each output giving you the 4 outputs needed for 61.5.
You'll need an extra dish for 61.5 with a DP Dual LNB, 4 DP21s and a couple of DP approved splitters.
Something similar to this picture but instead of the inputs will come from the DPP44 and not the DP Twin that's shown on the picture.
