FIX: The video may invert and turn green in Windows Media Player 10 (898549)


The information in this article applies to:

  • Microsoft Windows Media Player 10

SYMPTOMS

In Microsoft Windows Media Player 10, you play a multiple-bit-rate video stream. When Windows Media Player 10 thins the video stream by selecting a lower bit rate, the video may invert and turn green.

CAUSE

When Windows Media Player 10 thins the video stream by selecting a lower bit rate, sometimes Windows Media Player 10 must resize the video. When Windows Media Player 10 resizes the video, certain video formats give a negative size. This problem occurs because negative sizes are not appropriately handled in the underlying Microsoft Windows Media Format components.
