FIX: Windows Media Player 9 Series Seek Bar Has Zero Length on Certain DVDs (820771)


The information in this article applies to:

  • Microsoft Windows Media Player 9 Series for Windows XP
  • Microsoft Windows Media Player 9 Series for Windows 2000
  • Microsoft Windows Media Player 9 Series for Windows 98 Second Edition
  • Microsoft Windows Media Player 9 Series for Windows Millennium Edition

SYMPTOMS

Some DVD titles may not have a seek bar when you play the DVDs in Windows Media Player 9 Series. When the seek bar is moved, the video may be reset to the beginning. The titles include the following:
  • Toy Story 2
  • A Thomas Crown Affair
  • Lord of the Rings
You can still click the chapters listed in the Player user interface to move through the DVD.

CAUSE

This occurs because of a race condition in the Windows Media Player. When this occurs, Windows Media Player does not fire certain notifications because of a cached duration value. In turn, the Windows Media Player incorrectly sets the duration of the DVD title to zero, and this causes the seek bar to be disabled.
