My installer brought my HR22-100 Saturday. I was already overloaded on outputs from my WB68--some DVRs had only one lead--so I was hoping he could get me fully functional. I had previously emailed DirecTV in an attempt to make sure the installer knew what to bring. They said I could "rest assured" that he would have what was needed to make my equipment "fully functional" (canned response.) Once I saw how frustrated he was, I told him I understood and to leave it as-is if necessary, with just one coax going to the little-used DVRs. He ended up piggybacking two WB68s. It seems to be working right now. What will the symptoms be if it begins to falter? I did see one "searching for satellite" message when I changed channels yesterday, but the channel did come in. I have never seen that message except in bad weather. Is that the kind of problem I can expect? I understand I could use four power-passing splitters and parallel the WB68s if need be. Is that correct? Thanks!
