Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Software developers can work around this problem by using version 9 of the Video Mixing Renderer (VMR9) or the Enhanced Video Renderer (EVR) to render video.

VRM7, VMR9, and EVR are different mechanisms for rendering video in Windows-based applications. This problem occurs only when video playback is paused. This problem does not occur when a complete video is played or when playback is stopped.
