"DVD region codes are a digital-rights management technique designed to allow film distributors to control aspects of a release, including content, release date, and price, according to the region." (from wikipedia). There are six different official regions. DVD discs sold in a given place can't play in a different region. Most of the DVDs discs sold by Amazon.com are encoded for Region 1 and may not work in other countries. More information about the Region codes and countries, you can refer to : http://en.wikipedia.org/wiki/DVD_region_code.
In different regions, the Prometheus DVD release date differs, October 9 in US, and September 7 in Germany.
