I'm going to be housesitting for my parents soon, and I can't talk them into E*, they have cruddy cable... I would like to use my 7200 receiver, now in use with a SuperDISH, and hook it up to my old 18" and use at their house to get 119 sat. ( all I need). I can't get any signal at all (0 sig. strength) hooking up my 18 to my 7200. I get good signal with my SuperDISH, but even moving my 18 around does not give me ANY signal. Thinking I need to change a SuperDISH type setting on my receiver(?) LNB works good, tried with SuperDISH, RG6 cable good, any ideas on what i missed? THANX
