After many years of talking about it, we finally created the first test suite of files to validate Matroska players.

This set of files is as much of tool for developpers to make sure they have correct Matroska support in their product as for users to make sure the players they have (sometimes paid for, and advertised with Matroska support) is actually supporting Matroska correctly and will play any standard file (provided it can handle the codec).

We encourage anyone to download this test suites, give it a try in their favorite player and tell the world, through our mailing lists, our facebook group, our twitter, if it passes all tests or not.
