I don't have a Dish 1000+ yet and hoping for a Repoint Kit for my SuperDish 121; so I might be wrong, but I don't think that is completely accurate about the 118.7 needing to be in a particular port opposite the 119.
It is true that you would normally either put 119 or 110 in Port 1 of a DP-34 and DPP-44 when starting your dish adjustments (110 for SuperDish 121, 119 for SuperDish 105 and Dish 500+/1000+). This allows the signal to pass straight through. However, after you have your dish adjusted, I have not found where it makes any difference which ports you put them in....
Except for when the receiver is not compatible with more than a certain number of ports and/or not compatible with a certain satellite, such as:
One of your receivers only supports 119 and 110, then you should put those 2 in Ports 1 and 2.
If you have a receiver that supports 119, 110, and 61.5, but not 129, 121, 105, or 118.7; then you should put 119, 110, and 61.5 in the first 3; and put the 4th in Port 4 for your other receiver.
Likewise, if you have one receiver that only supports 119, 110, and one 129; and a second one that supports those 3 plus 118.7, then to get both receivers to work, you need 118.7 on Port 4, and the other 3 shouldn't really matter.
