Well, as an enthusiast, I suppose one might make a bigger
deal of minor differences. And even at that, as you say,
there aren't big differences.

But I was referring to the *broadcasters*, and their
insistance that HD be carried on cable systems as HD. Do
they care, whether it's 1080i or 720p? Or is this just
a pretext to create a problem with must-carry when no
problem should exist?

In other words, a smoke screen.

I mean, audio enthusiasts also insist on using single-
ended triode tube amps of 5 watts output, but that
doesn't mean that FM broadcasters must also use tube
electronics and single-ended circuits.
