the main geneie uses a different dish than the old receiver, they did put up a different dish didn't they. my son was an installer for direct and he is setting me up with a D12 receiver which is not HD and it is easier to align the dish when setting up. you can buy a old receiver from direct tv and they only charge you $6 a month to use it in your RV. too bad you didn't keep your bedroom receiver. now you have to buy one and pay a monthly fee to use it. if you had kept the old one you would be home free.
