Windowboxing (different from pillarboxing) helps you see the "full picture" even on TVs with factory-set overscan. That's the advantage.
"4:3 anamorphic" DVDs may be seen now and then where, after windowboxing a 4x3 film onto a 1.85:1 frame, the resultant frame is coded anamorphically -- though this results in reduced resolution. The advantage is that when you play this off a DVD player that's set to 16x9 -- onto a 16x9 TV, you get a picture in proper aspect ratio without any aspect distortion.
However, new blu-ray players can do a "smart play" for 4x3 movies by automatically generating pillars on left and right.

Try playing your DVDs with different settings on your player -- are you playing them off a DVD player?
I've played all of them on a blu-ray player and the windowbox appears automatically. When zooming in from the TV settings I can get it appear letterboxed.
