What you might be seeing is broadcasters trying to 'cheat' on their
production of both SD and HD feeds of the same show. I saw this last night
on some station. While watching a show in SD, there was a degree of
letterboxing, but it wasn't enough to be 16:9 on the display. I suspect they
were just downcasting the HD 16:9 feed and dropping some of either edge of
the picture to mostly fit on a SD 4:3 format. Hard to describe in words, but
when you see it you know what I mean.
