My guess is that they want to be in control so I don't think you can just attach anything you want to the system.
Just bought Hatachi 50V500 and DirecTv+Tivo DVR, I am now lead to beleive that I need a multiswitch between new LNB(2 outputs) and 2 inputs of DTV unit in order for the sat. receiver to "see" a signal and thus pass the initial setup test.
Second related question is; because I am dedicating this LNB only to my HD setup, will the system allow me to use a second multiswitch, or does the DTV system want to see the same multiswitch in use on all LNB's??
Thankful for all input, suggestions...
