FIX: When you use an application to play DRM-protected video content in Windows XP, the application may fail

Support for Windows XP has ended

Microsoft ended support for Windows XP on April 8, 2014. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

SYMPTOMS
Consider the following scenario:
  • You are playing Digital Rights Management (DRM)-protected video content in Windows XP.
  • The content was protected by using the Microsoft Windows Media Rights Manager Software Development Kit (SDK).
  • You have DirectX video acceleration (DXVA) turned on.
  • The application that you are using to play the content uses DirectX for video playback.
In this scenario, the application may fail.

Note This problem does not occur if you use the following applications to play the DRM-protected content:
  • Microsoft Windows Media Player
  • An application that was written by using the Windows Media Format SDK
CAUSE
This problem occurs because of the way the Windows Media DirectShow QASF filter handles content that is both interlaced and protected.
