I have two local stations in HD and two in SD. For many months now, whenever I tune to any of them, all four are visible on one tuner -number 3- on the TV activity page. Since I could manually record all prime time programming every night, using only one tuner, why isn't PTAT available for all four networks for me. Only ABC and CBS - the HD stations - are available to record with PTAT. Actually that's not exactly true, I have actually used PTAT to record all four networks twice. Most times I go to the PTAT programming page, NBC and FOX are grayed out. But sometimes they are available to check. Twice this has worked and all four networks have recorded, but every other time, when I checked back to the PTAT programming page, NBC and FOX where grayed out again. Since all four networks are on one tuner, why no PTAT, Dish?
