It doesn't. It simply can't. PTAT simultaneously records our locals off of a single, satellite transponder. Now, AutoHop does still work (after the usual time allowance imposed by each network).
Hey, the 612 is a great receiver as well. I have two 612's and a 722 which gives me 3 OTA tuners and 6 sat tuners. How much would that cost me if I were to switch to a Hopper with a GUI I don't even like?
