i bought the slimline 5lnb dish with four outputs and the hd receiver. i am changing from the the 18" round dish. we are using one hd box and 5 standard boxes. the splitter we have is from the old dish. we receive a signal of 95 to 100 on the test of the round dish. nothing from the new slimline. i haven't a clue how to hook it up or what i need to even begin to make the new box and hd television work, what satellite dish to set up in the setup menu and how to run the wire from the dish to the house
