Let me see if I can clarify it a little for you. Someone posted a link as
well, and it should be good reading. Not all digital broadcasts are HDTV.
Many are standard definition (480i).

4:3 Standard definition digital broadcast. Is not HDTV, only DTV

> 2) 16:19 full screen but low quality HDTV picture

16:9 stretched or zoomed standard definition broadcast, not HDTV, only DTV

> 3) 3:4 screen ratio, 720p, good quality HDTV picture

4:3 720P HD broadcast of a standard definition source material

> 3) 16:9 ratio full screen, 720p, good quality HDTV picture

OK

4 and 5 are the same thing. The perception of quality can be due to the
type of output you are watching. An example would be that some films have
granular effects on purpose.

Thanks for the information. I'll read up on it.

You'll also discover that some 1080i channels appear better than others
like Discovery HD, InHD, InHD2, and HBOHD. I'd guess that they use
those "IMAX cameras" and are much, much better than the others.

WETAHD is probably one of the worst 1080i broadcasts out there, though.

What is the ratio when you get full (widescreen) but only the middle 2/3's
of your screen. Pay for view from Dish last night.
