Warum funktionieren manche CDs, DVDs und Blurays nicht in allen Ländern?

Die haben einen sogenannten Region-Lock.
"Eingesetzt auf DVD-Video und Blu-ray Disc, soll er verhindern, dass auf diesen Medien gespeicherte Filme weltweit abgespielt werden können. Dazu wird durch geeignete software- oder hardwarebasierte Vorrichtungen überprüft, ob ein Abspielgerät den gleichen Regionalcode besitzt wie das eingelegte Speichermedium."
Wohl um zu verhindern, dass die Inhalte in Ländern zur Verfügung gestellt werden, in denen man u.a. keine Lizenzgebühren kassieren kann.
"One purpose of region coding is controlling release dates. One practice of movie marketing which was threatened by the advent of digital home video was the tradition of releasing a movie to cinemas and then for general rental or sale later in some countries than in others. This practice was historically common because before the advent of digital cinema, releasing a movie at the same time worldwide used to be prohibitively expensive. Most importantly, manufacturing a release print of a film for public exhibition in a cinema has always been expensive, but a large number of release prints are needed only for a narrow window of time during the first few weeks after a film's release. Spreading out release dates allows for reuse of some release prints in other regions.
Also, the copyright in a title may be held by different entities in different territories. Region coding enables copyright holders to (attempt to) prevent a DVD from a region from which they do not derive royalties from being played on a DVD player inside their region. Region coding attempts to dissuade importing of DVDs from one region into another."

Im englischsprachigen Wikipedia steht es mal wieder genauer beschrieben. ^^
"DVDs, and many other goods, are sold at significantly different prices in different areas of the world. (There are also differences in release dates, to which this reasoning also applies.) This price discrimination allows the DVD sellers to make as much money as possible. Without region locking, it would be easily possible for a third party to buy up a lot of English-language DVDs sold in India, for example, and sell them in the US, undercutting the "official" vendor, but still at a higher price than they bought them for. This is called arbitrage. To prevent people from doing that, manufacturers of DVDs and DVD players invented the region-locking system, which prevents legitimate DVDs you buy in India from being watchable by US viewers."
