Query: You can't win...

There are 2 models made by different companys but look the same. This model the 600 series doesn't allow you the flexiblity to program it even from Direct TV. The 100 series works better but it's already been phased out. The newer HD reciever from Direct TV doesn't have an off air antanna connection. You can't win.
