Audio may not be synchronized with video playback when you play a video in Windows Vista
When you play a video or a DVD in Windows Vista, the audio part of the playback may not be synchronized with the video playback.
You may experience this issue if one of the following conditions is true:
- The computer processor has characteristics that prevent it from playing the video at the selected frame rate or resolution.
- The computer has a processor that has power management features, and the active Windows Vista power plan slows the processor to maximize battery life.
Playback of multimedia content may require large quantities of processor resources. These kinds of multimedia include high-definition video, DVD video, and some audio formats. The processor may be unable to deliver the required performance for video playback depending on the resolution and frame rate of the video. Audio playback may not be synchronized with the video playback.
Additionally, Windows Vista enables processor power management features that reduce processor performance to help extend computer battery life. By default, Windows Vista reduces processor performance when the active power plan is set to
Power Saver, and when the computer is running on battery power.
To work around this problem,
change the active power plan to
Balanced or to
High Performance.
Note If you change the power plan to
Balanced or to
High Performance, you may reduce the battery life of the computer.
To change the active power plan to
Balanced or to
High Performance, follow these steps:
- Click Start

- Under Select a power plan, click Balanced or click High performance.
Note The computer manufacturer may have changed the names of the Windows Vista power plans.
By default, Windows Vista enables processor performance states when the active power plan is set to
Balanced or to
Power Saver. Processor performance states enable Windows to reduce processor performance to help extend system battery life.
In the default
Balanced power plan, Windows Vista uses all potential processor performance states based on workload demand. In the default
Power Saver power plan, Windows Vista keeps the processor at the lowest performance state to maximize system battery life.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
