Video Playing gets stuck | Video not in sync with Audio | Video doesn't match Audio | Solution

This is one of those frequent issues where in we cannot play video smoothly. Maybe its any file, when you play a video, it gets stuck once every 4 sec or any time. The sound keeps going on. But the video doesn't move and after sometime, it automatically moves to next spot wherein it can match the sound.

I have faced this issue so frequently and I was frustrated. This happens to the High Definition videos like MKV (x264 format) files predominantly as they demand more system resources. Anyways, below is the best solution for this. Please note that the exact software updates will be provided later. But this is the fix.
Just follow these simple steps to fix this issue:

1. Have your current drivers backed up. Use any good software like Driver Scanner or Genius. I will provide the links to these later in my forthcoming posts.
2. Ensure you have latest directx 9 (2009 March Edition is latest when writing this post). So download the latest directx. Install it. This should solve your issue.
3. If re-installing the directx doesnt solve the issue, Uninstall your Video Card drivers by going through the Device manager. Install the latest drivers suitable for your chipset. Below are the links wherein you can download the latest drivers:

Download - NVidia Drivers
Download - ATI Drivers

I dont think anyone can feel the HD Experience without a Graphics card as it has its own memory. Hence only provided these links. Onboard chipset users, go to your manufacturer's site.

4. If needed reinstall the latest drivers for all the hardware configured. Not to forget the latest Audio Drivers as well.
5. After this, Re-install the latest directx. Restart the system. The Sync issues should go and you must be able to playback smoothly any video.
6. Still if its an issue, might be an issue with the player but this would be very rare. Suggested players are KMPlayer and VLC older version. (Latest is bloated)
7. Still an issue? Then maybe an OS Issue as mine was the same. Last resort is to reinstall the OS after format. Install the latest Drivers always. But only, the right ones!
8. Still an issue, might be related to hardware like the overheat, Temperature issues etc.,

Please comment if you need any assistance in these as I have solved on my own and so writing this. Most of the issues must be fixed by doing this.
