I got a Genie set up a couple years ago when I finally went from SD to HD. They put up a new dish (a bigger, eliptical shaped one) and ran a bunch of cables into the house. In my basement I have a black box labelled as a "SWiM" that has two coax cables hooked to it and it plugs into a wall socket for power. One of the cables runs to a splitter device labelled as a "SWiM-8" and from the splitter two cables go my HR34 Genie. I have three other small boxes in the rooms upstairs that all connect up to this splitter (I think). The HR34 over the last year or so has gotten incredibly slow to respond to anything. Just bringing up the channel guide can take anywhere from 10 seconds to a minute. Fast forwarding or rewinding recorded shows is a painful experience, often going way past where you want to stop, and sometimes I can't get it to stop at all. Recordings get a lot of pixelation, or noisy pops, and sometimes the recorded show will just freeze for several minutes. I have tried every "fix" I can find from resetting it, to wiping out all recordings to clear the disk and various things posted here and in other forums to no avail, so I got fed up and called DirecTv. They agreed the HR34 needed to be replaced and I received a new HR44 today, and thus my question: The HR44 only has a single cable input where the HR34 has two. Do I just plug in one of the cables and it will work?
