I watch every Jackie Chan's films since I was 15 years old. I first watched Police story was on a VHS tape and the quality of sound was not that good as DVD. Jackie Chan's Kongfu was great and this is also one of the reasons why I love his films. I like Chinese Kongfu and Jackie Chan just made the fight on the screen. with this DVD release, at 101 minutes which means there were some added scenes compare with VHS. You will get a better sound quality no doubt.
