MP can't see ffdshow

[WTCYoStunt12]

All is in the title.

I download ffdshow on sourceforge then I install it in "C:\Program Files (x86)\"

I launch maniaplanet, in the hope to find ffdshow in the shoot options, but MP can't see it.
I thought I install the program using a bad way but I do exatly what I have to do to install it (that sentence).

Can someone help me ?

Make sure to use 32bit version here http://ffdshow-tryout.sourceforge.net/download.php
ManiaPlanet is 32bit, therefore 64bit version won't work.
And the original ffdshow is totally outdated and did not work for me either.
