I just moved into a new house and did the whole movers connection thing. I have 2 HR20s that I moved from my old house, upgraded my HD Tivo for a HR23, got a standard DVR and a D12 receiver. The installer used a SWM. After the installer was done, he told me there appeared to be a tree that was interfering with the signal so I was getting some breakup and that it would only happen with the HD channels. After he left and I started watching the multiple TVs, I realized the breakup (searching for signal) only occurs on one TV (with one of my HR20s). The others are fine. In addition, it isn't just the HD channels that are a problem. This morning I was watching channel 291 (DisW) and msnbc keeping breaking in. I've never seen that happen! Always before when I have had tree problems, it affected all the TVs in the house. Any ideas on what the problem is? I figured I would post here and get some suggestions before I call Directv.
