To All: I am getting Direct TV installed Thurs. I did have a Dish 625 dual tuner DVR. The Dish 500 antenna had 2 cables off of 2 LNB's. They went into a splitter (combiner?) and just one RG6 went into my house. Just before the DVR it goes into another splitter and 2 short RG6's went into 2 separate input's that went into the box. Will the installer be able to use the existing cables to install the Direct DVR?
