Considering the following scenario:

• You have a computer that is running one of the following operating systems:
  • Windows XP
  • Windows Vista
  • Windows Server 2008
• This computer has a Texas Instruments (TI) IEEE 1394 host controller installed.
• On this computer, you install hotfix 952824 or hotfix 951410.
• On this computer, you connect one or more IEEE 1394 digital video cameras or other isochronous streaming devices.
• You use these streaming devices to stream some data.

In this scenario, the device performance decreases. For example, streaming speed may become very slow, or some frames may be dropped.

On a Windows-based computer, devices that stream data over more than two isochronous channels by using IEEE 1394 connections may have choppy or distorted output. Typically, the issue occurs when multiple instances of isochronous data, such as audio data and video data, are streamed over the IEEE 1394 connections.

Note: This problem may also occur on a single physical device that has multiple channels of isochronous data. For example, this problem may also occur on an audio mixing board that outputs multiple audio channels over separate isochronous channels.

For example, you may have multiple digital video cameras, audio input devices, or both, that are connected to the computer by using the IEEE 1394 connections. In this case, streaming video that is output from the digital video cameras may appear choppy and may not have a smooth and steady frame rate. Steaming audio from the audio devices may have distorted sound.

After you install Windows Internet Explorer 7, you may experience either of the following symptoms:

• Symptom 1

  When you try to download files by using Microsoft Windows Media Player, you may receive an error message that resembles the following:

  Windows Media Player cannot access the file. The file might be in use, you might not have access to the computer where the file is stored, or your proxy settings might not be correct.

  If you click the option to request more information, you may receive a message that resembles the following:

  You’ve encountered error message C00D11D2 while using Windows Media Player. The following information might help you troubleshoot the issue.

  Cannot access the file
  Windows Media Player cannot access the file. You might encounter this error message for one of the following reasons:

  • This file is currently in use. Close the file, and then try again.
  • You do not have permission to access the server or other location where the file is stored. Verify that you have the appropriate access rights, and then try again.
  • You do not have permission to access the proxy server. Verify that you have the appropriate access rights, and then try again
  • You are trying to rip a track from a CD to your hard disk and you do not have permission to rip to the specified hard disk location. Verify that you have the appropriate access rights, and then try again. If the problem persists, try ripping to another folder.
• Symptom 2

  When you try to watch a streaming video from a streaming service in Windows Media Player or in Internet Explorer 7, the streaming video does not play to the end of the video.

These problems may occur if the following conditions are true:

• Windows Media Player downloads files by using a server-side playlist (SSPL).
• The server is running Microsoft Windows Server 2003 and Windows Media Services 9 Series.
• The Windows Media Services 9 Series server has fast-cache enabled.
• You try two times to download a file that has the same URL name. Or you try two times to stream a video that has the same URL name.
