i'm not sure if you guys will understand this but i'm having a major problem and i need help. ok this is what is going on. i just upgraded to a kaku dish and got a h20-700. i also have 2 tivo boxes not HD and 4 old boxes. when i connect everything i loose every other HD channel from 70 and up. i changed the hd box and directv came out twice and have no clue what to do. when i take out 4 of the wires that are going into the switch it starts working again. if i plug any one of those 4 wires to the switch the hd channels go out again. anyone have any clue what can be going on and how i can fix it?
