I have a vip722 hooked up to a 1000.4 on the eastren arc. My locals are Knoxville, TN on the 110 satelite. I added a dish pro 500 to the 4th port and pointed it to 110. I ran a switch test and I am getting a good signal from 110 on port 4. When I try my local channels the receiver is trying to get them off of 61.5. How do I get the receiver to look for the channels on 110?
