iTunes users outside of the US often get the short end of the stick when it comes to which media Apple makes available to them. This is usually due to licensing issues with the record labels or TV/movie studios. So when Apple rolls out some of its services internationally, users don't always know what to expect. In the case of iTunes Match and iTunes in the Cloud, however, Apple has decided to make things clear by posting a detailed support doc that outlines exactly what can and cannot be accessed in each country.
[partner id="arstechnica"]As usual, US users of iTunes in the Cloud have access to everything—they can re-download their music, TV shows, music videos, apps, and books from the iTunes Store from any iOS device at any time. The UK, Canada, and Australia also get all the goods. A number of countries—mostly ones in Latin America and Europe, with a couple others sprinkled in—can re-download everything but TV shows, and most of the remaining countries only have access to apps and books. Apple's support doc also specifies each country that has iTunes Match available to them (in case users there weren't already aware).
The document should help clear up some confusion as to why users in certain countries can't re-download certain types of media.
