Can someone please help me with setting up a KAKU direct tv hdtv sat 5 lnb dish and system. I currently have just a regular dish (non HD)with 2 cables that go all the way to my dvr. This new dish has 4 cables and I am completely unfamiliar with HD. Someone told me I need a LNB switch? Others told me I do not. I am going to order a new HD DVR from direct tv but need to see how difficult the install will be...Can anyone give me HD Satellite installation instructions for dummies type of help....please.....
