Message: [QUOTE="shill, post: 1583149, member: 22628"] There are two coax cables coming out of my wall plate, only one is hooked to anything. The one that is plugged in is hooked into one diplexer which splits the cable into two. One of those signals is going to the "home distribution" area of the 722, the other signal is then channeled into a splitter which makes two more coax cables going into Sat 1 and Sat 2 of the 722. I am running HDMI to my main TV. I know this sounds stupid, but is the second cable coming out of the wall plate supposed to be plugged into anything? (It's not). [/QUOTE]
