I've been watching some older television shows on HDNet (Square Pegs, in particular) and have noticed that the image fills almost the entire screen (with VERY thin black bars on either side of the image). obviously, the original aspect ratio was 4:3, correct? so are we missing a small portion of the original broadcast picture on the top and bottom? i ask because the image does not look to be stretched at all.

Seems kind of odd b/c HDNet is always bragging how they always use OAR.
