DVDs
"The BBC has reported that "After docking, the shuttle crew of five astronauts delivered supplies and gifts to the Alpha crew, including a computer, cables for the laboratory, food, water, clothes and about 20 DVD movies." in this story, which raises the interesting question: what DVD region is the International Space Station?" So, either they have a region-free DVD player - which is theoretically illegal according to Hollywood - or only the U.S. crew gets to watch movies.
