SYMPTOMS
When an application delivers licenses and sets Digital Rights Management (DRM) technologies to allow for transcription, the application leaks memory in the Microsoft Windows Media Format 9.5 software development kit (SDK). This problem occurs when the application sets a valid GUID by calling the IWMRMRestrictions.AddInclusion method, and then the application calls the IWMRMRestrictions.GetInclusionList method.

If the application does not set a valid GUID by using the AddInclusion method, the memory leak does not occur.



CAUSE
This problem occurs because the application incorrectly frees memory on one of the Windows Media Rights Manager objects.
