Rescored Music on Laserdisc

Rating: Null/10 (7 December 2003)

A decade ago, before the DVD era, I was at a video store where I noticed, on the back cover of a JAWS laserdisc, the message "Some Music Rescored". Later, I found that due to some copyright issues, some music on this edition of the LD had indeed changed. Since then, I have been wondering what part of the music this was.
A few days ago, I finally broke down and bought a cheap copy of this edition of the LD from ebay. I played back every part of the movie that I knew had background music, and did not notice anything different from the version that has existed for the past 28 years.
What is this new rescored music, and where in the movie is it? If you know the answer, I would appreciate a reply. This is bugging me!
Thanks in advance.
