I'm trying to troubleshoot an issue with our DirecTV boxes. We have an H44-500 Genie in the living room, and a C41-700 mini-Genie in the den. My wife complains that the closed captioning in the living room does not work well. So, I wanted to swap the 2 boxes to see if the issue is a box problem, but when I try to connect the Genie in the den it doesn't connect to the antenna. There is a single cable coming from the LNB to a splitter, which then sends the signal to the 2 rooms. So, it shouldn't matter which cable connects to which box, but apparently it does. My other option would be to lug the den TV into the living room and connect it to the Genie, but that is more work!
