DVDs are coded by region. For instance, I wanted to see what all of the fuss was about with Kubrick's last movie featuring Cruise. A scene was censored only in the United States so I went out and bought a Zew Zealand release but I had to get a region-free DVD player to watch it. (Something to do with the hand-jive....)
Thw studios want to stagger the release of movies world-wide so The United States is region one and there are numbers for each part of the world. this will maximize profit as DVDs could be released in the USA while the movie premieres in Australia. A DVD player is set to work movies from that region, but not others.
My Apple computer will play DVDs from all regions until I have played four of them and then it sets itself to that (last played) region.
There is a web site, I don't remember it's address where you can download instructions to re-set your DVD player to another region or to '0' which is region-free.
