But back to my original point. Satellite receivers have never (to my knowledge) had NTSC receivers in them, even BEFORE D* and E* started offering locals. This, of course, is because everyone had a TV or VCR that already had one or more NTSC tuners in it, and DVRs were few and far between.
Right now, ATSC tuners are still fairly rare, and, by putting them in their receivers, E* and D* are sweetening the pot for HD subscribers who can utilize them, especially because neither is able (at this moment) to offer HD locals. This is a great situation for consumers, because E* and D* are able to offer an integrated DVR solution for satellite and OTA.
Fast-forward to MPEG-4 times. Both E* and D* are offering HD locals. Why would they now want to put OTA ATSC tuners in their receivers? By that time, their customers will no-doubt have several ways to receive HD OTA, but only ONE INTEGRATED DVR solution - satellite LIL's.
