In short, there were quite clearly different Pan and Scan cuts of the films as this one example shows.
The Pan and Scans are not "bad".
In fact, for most people, these versions were the ones first bought/recorded from TV in the 80's and played again and again until they fell apart.
After that, the widescreen versions just did not look right (on a normal 4:3 ratio TV) and only really look the part on the widescreen TV's that are now more common place in 2007.
Here is another page of interest.
