K-Lite Codec Pack crashes games when playing in-game videos

Several months ago, I updated the K-Lite Codec Pack and found out my game would crash when playing in-game videos. At that time, I simply uninstalled the new version, and got back the old version.

Two weeks ago, I decided to give the new version of K-Lite Codec Pack another try, and would like to see the problem has been solved. Unfortunately, nothing changed but crashing games. The FAQ on the official website of K-Lite Codec Pack provides some solutions (, but all failed to solve the issue.

What I suspected was that it is related to the configuration of the software. I checked the video format of the games, it is wmv videos. So I  did the following.
  1. Opened the Codec Tweak Tool that comes with K-Lite. 
  2. Clicked on the Preferred splitters (under the section of Codec and Filter Management
  3. In the pop up window, there are two columns ## 32-bit source filters ## and ## 64-bit source filters ##
  4. Found out the .wmv section (both 32-bit and 64-bit sections), changed the setting from Use merit (recommended) to LAV Splitter
Problem was solved.

Update: Apri 2015
In the recent version of K-lite, you may need to change the VC-1 section instead of wmv. You can use MediaInfo tool that comes with K-lite to find out the detailed information of the game videos.
