There are several different movie aspect ratios. The ones that most closely fit a 16:9 widescreen TV are 1.77:1 and 1.85:1.
Some filmmakers (George Lucas, among them) prefer to use a wider format (like 2.35:1 or 2.40:1), since that more closely matches the human eye's field of vision. You probably rented some 2.35:1 "super-widescreen" movies, and hence saw some letterboxing.
