Have you checked what type of switches your "point dish menu" says ? If you still have SW21's to get 119, 110 and 148, I'd almost certainly bet that you now have a TWIN. Yes the TWIN should work on both if you're "Check Switch" has 34 tests.
#2 - If you have a TWIN, then you're screwed right now for going beyond 2 receivers - you'll probably find it cheapest to buy 2 Dual LNB's (and a Dual LNB on the 148 dish), and get the SW64.
#3- Supposedly, you COULD switch to the DishPro equipment, but seriously, you'r going to need the following - DishPro Twin for 119/110, DishPro Single for 148, DishPro DP34, then 1 Legacy adapter for the 4900 and one for the DishPlayer (if it will work there ?). The Legacy adators alone are going to cost you $70 each.
