First off i want to say all the info I have gotten from here has been very helpful. My question is this: I have upgraded my 211 receiver to the 722. I had them send me the 722. I have the dish 1000 already. I have rerun the cables already to where the 722 is going to be. So basically i have the 2 cables coming from the dish to where the 722 is going to be. Also I have the 2nd sd tv cable going from the 722 to the receiver. In order to hook up this up do i put the 2 cables on sat 1 and 2 on the 722 or do i need the sat 1 and 2 splitter. Do I need the diplexers outside anymore since im not backfeeding another tv.
