Pardon my ignorance, my problem is I upgraded the dish to the slimline last summer so I could get HD on my new tv. I have one other receiver that is the bedroom. So I ordered another receiver and received yesterday, I got the wb68 multiswitch also. I can't get the new receiver to work, and also my hd is not coming in. Looking at the dish, I only see 2 cables going into the house. Should there be 4 cables running into house? Thanks for any help
