No better comparison, I agree completely. Too bad we have no
such comparisons available to us today that mean squat.

Again, no valid comparison is available, so there's no point
bringing up those old results. All we do know is that the new
ATSC receivers are considerably better than those used in
those old tests, specifically in the areas where those old
receivers did poorly. So we do know that if *these* 8-VSB
receivers had been tested against *those* COFDM receivers,
the results would have been *CLOSER*. That's all we know,
and that's all that matters at this point.

If I remember correctly, the FCC conducted its own set of tests
before making that decision, and we discussed those FCC results
on OpenDTV. And the FCC also made the assumption that 8-VSB
receivers were improving. Well, from where I sit, this is
exactly correct. Receivers were and are getting better, and
they are getting better in performance measures that were poor
before. Is there any point in continuing to point to some
company's overly hyped press release of 4+ years ago?
