mkv codec

[ERWAN]

I am looking for a codec, which can work with Windows Movie Maker, I have currently installed one in my system, which is working fine with Windows Media Player, but its not supported by Windows Movie Maker, can you please help me or provide some information regarding the same.

Well I really have a doubt about the same, but one thing you can do is you can convert the file in Windows Media Player.
