Thats your setup Dave... not the networks or dishnet. Are you
running your input to the TV to the coax/antennae input? ( RF on
channel 2 or 3)

No, my "input" goes to the converter box, the output of which goes to
my DVD burner via COAX then out to the TV via a video RCA jack.

So your input to DVD burner is analogue RF channel 2 or 3. You
realize that is the lowest possible rez video? Then you send it out
via composite video which is the 2nd lowest rez possible. Then your
digitat TV tries to digitize and reconstruct from this crap.

I get the same artifacts when going directly from the converter box to
the the TV (which isn't digital, BTW). I have two choices, COAX or
RCA, and I don't have the choice of component video.

With a still picture... most pixels not changing... it does ok. With
sports the whole damn thing breaks down as the TV can't digitally
reconstruct fast enough when all the pixels change. My son-in-laws
plasma looks like hell on sports before he upgraded his cable box and
got one that supports component video. The cable guys says DVI didn't
look any better to him.

Anyway... the problem is your setup... not the network. I can watch
all that stuff with none of the artifacts you see.

Do you have TIVO-esque capabilities?

Still, I'm saying that there are DEFINITE compression artifacts in
certain programming and not in others (or far less). This implies that
it's content driven, not delivery driven. Some of it COULD be hard
drive related though, since I don't seem to have ANY programming that
I could confuse with DVD.

And you said "cable guy". I'm talking about satellite service, NOT
cable. I can't do a direct comparison, but I don't remember such
artifacts when I had cable.

These
artifacts are DEFINITELY not cable or transmission dependent, but
content dependent, because, if they were, they'd be uniform regardless
of channel and they aren't. All I have to do is compare ESPN to The
Tonight Show, for example.

They are content dependent in the amount of picture area that changes
at once. Let me guess... basketball with half the screen being crowd
and tracking a length of the court pass goes all digital artifacty...
lots of little squares before the TV can smooth it all back
together..... if your "box" supported S-video or Component video out...
you wouldn't have these problems.

Well, it doesn't. Either capability.

What kind of TV do you have?

A simple current Toshiba 32 incher.
