Working with Motion Blur

Ok !

I was working to implement a way to use Motion Blur Effect in a mini game and some how managed to implement that,But now it is out of control.
can some one help me and show how to control the motion blur using python scripts?

And i would be delighted if, there are any tutorials on 2D Filter actuator and use Custom 2D filters…?

Thanks!
