MEIndividualizationStart event

Raised by the policy engine when individualization is about to begin. Individualization is performed using the application's implementation of the IMFContentProtectionManager interface.

An individualized application is one that has received an upgrade to its digital rights management (DRM) components that differentiates it from all other copies of the same application. Content owners can require that their protected files be played only on an application that has been individualized.
