SYMPTOMS
When an application helps protect content files by using Microsoft Windows Media digital rights management, the digital rights management-protected files may not play back correctly on some Microsoft Windows Media DRM 10 for Portable Devices-based devices. This problem occurs when the application is built on top of the Microsoft Windows Media Format 9.5 SDK. This includes applications that are built on top of Microsoft Windows Media Encoder 9 Series with the Windows Media Format SDK installed.



CAUSE
The Windows Media Format SDK does not write a Unicode prefix before the DRM version 2 header starts.
