Windows 7 Audio and video out of sync in wmp and mc

[supersimen]

When I use wmp or media center, the video is shown slightly earlier than the sound. Probably around half a second.
Its nothing wrong with the files, they play perfectly in vlc. This goes for all .avi files, whether its backed up movies, or tv shows.

You might say that this is not really a problem and just another reason to stop using wmp. But I really like Media Center. I often connect my pc to my flatscreen tv and it is incredibly annoying to watch movies out of sync.

I use windows 7, x64. I have 4 gigs ram. 2 gHz dual core intel centrino 2. 9600m 512mb nvidia graphics card. Its an acer notebook, 5930g.

I have tried another pc, with windows 7 x86, and it has the same problem. I've tried to change decoders, including Nvidia purevideo, and codecpacks.

I have also tried to tick the performance settings in wmp, drop frames to keep in sync, and smooth video. This works perfectly till open a new file, or start over, or skip in time. And I mean just changing them works, does not matter if I set them on or of, the change it self works until i stop, or just pause.

This is incredibly annoying, and I hope there is someone who has similar problems and have a solution

The issue you are facing where the video is displayed slightly earlier than the sound in Windows Media Player (WMP) or Media Center can be quite frustrating, especially when watching movies on a TV. This synchronization problem is common and can be caused by various factors related to codecs, drivers, or settings. Here are some steps you can try to resolve the audio-video sync problem:

Troubleshooting Steps:​

1. Update Codecs:
   • Make sure you have the latest codecs installed for playing media files. Sometimes outdated or incompatible codecs can cause sync issues.
   []Adjust Playback Settings:
   • In WMP, try adjusting the playback settings. Right-click on the playback screen, go to Enhancements > Play Speed Settings, and adjust the sync offset to synchronize the audio with the video.
   []Check Audio Drivers:
   • Ensure that your audio drivers are up to date. Outdated audio drivers can cause audio sync issues. Visit the manufacturer's website to download and install the latest drivers.
   []Disable Exclusive Mode:
   • In Windows audio settings, disable exclusive mode for the playback device. This can sometimes affect the synchronization between video and audio.
   []Use External Players:
   • If the issue persists, consider using external players like VLC media player, which is known for excellent codec support and playback reliability. VLC often handles sync issues better than WMP.
   []Adjust Video Rendering Settings:
   • Check the video rendering settings in the graphics card control panel. Sometimes adjusting these settings can improve synchronization.
   []Update Graphics Drivers:
   • Ensure that your graphics card drivers are up to date. Graphics driver updates can sometimes address audio-video sync issues.

     Additional Tips:​

     • Restart your computer after making any changes to settings or drivers to ensure they take effect.
     • Test different files to see if the sync issue occurs with specific file formats or all files.
     If the problem persists after trying these steps, consider switching to an alternative media player like VLC for a smoother playback experience. Let me know if you need further assistance or if you have any other questions!
