Play video or DVD audio and video out of sync solution in Vista

                  When playing high-definition video, DVD-Video, and some audio formats in VISTA, there is a loss of audio and video.

This is because when the multimedia player may take a lot of processor resources. These types of multimedia include high definition video, DVD video, and some audio formats. Depending on the resolution and frame rate of the video, the processor may not be able to provide the performance needed to play the video. As a result, audio playback may not be synchronized with video playback. Computer processors have power management capabilities, and Windows Vista's current power plan maximizes battery life by reducing processor speed. So, if we want to solve this problem, we can try to change the current power plan to "balanced" or "high performance." The specific steps are as follows:
1. Click “Start” and find “Power Options” in the “Control Panel” list. (If you are prompted for an administrator password or for confirmation, type the password or click Continue.)
2. Under Select Power Plan, click Balanced or High Performance.
