Consider the following scenario:

• On a multiprocessor system, you encode a multi-bitrate (MBR) video by using one of the following:
  • Windows Media Encoder 9 Series
  • An application that is based on the Windows Media Format SDK

You compress the video by using one of the following:

• The Windows Media Video v9 codec
• The Windows Media Video 9 Advanced Profile codec

When you use Microsoft Windows Media Player 11 to play a Windows Media Video (WMV) file in Windows Vista, a vertical line may appear in the middle of the playback window. The line appears as a band or a bar. The band or the bar is discolored with blue or with green. You may also see other artifacts or corruption in the playback window.
