So I recently got my first HDTV. We've had DirecTV throughout the house for almost ten years, but of course it's been the plain old SD service the whole time. I of course want to upgrade to HD now to get the most out of my new TV. I know that along with the HD service I need a new dish and receiver to watch HD programming. But there's also two other old TVs in the house that don't need the high-def. So my question is, with HD service do all the receivers in the house have to be replaced to continue to receive programming, or will the D12's still work with the new dish?
This is pretty much the make-or-break factor, as I can't afford to replace every receiver in the house, at least not all at once.
Thanks very much for any help!
