Directv HD format?

Question

with Directv's HD channel line up, most of the programs are shown in pillarbox 4:3 ratio, which is weird because the SD duplicate is stretched to fit the screen, why do they do this seeing as you know most HDTV's are widescreen? Can you set it to fill the entire screen?

Answer 1

A lot of programs were made in std 4-3 ratio they can't be streched to fit the screen, if they did people would look fat
