Whats the difference between 4:3 Letter Box and 4:3 PAN Scan

Can someone please tell me whats the difference between 4:3 Letter Box and 4:3 PAN Scan when choosing your Screen Size in DVD options? Thanks

It's pretty much what it sounds like - the image is intended to be played on a 4:3 box (your standard TV, not a widescreen tv). The Pan & Scan version takes the original movie and crops pixels to give you a full screen picture, but missing some of the movie, while the letterbox version reduces the size of the picture so that you see the full movie but have black bars top and bottom.
