The disk itself is unregioned (region 0) but contains a script which checks the player's native region instead. This protection has been added to recent and soon to be released DVDs including Close Encounters of the Third Kind, Crouching Tiger Hidden Dragon and The New Stanley Kubrick Collection, so watch out if you bought a region-free player. A list of known-compatable players can be found back on this page." "Enhancement" seems to be pretty high doublespeak in this instance.
