This is what happens when I browse for ffdshow.ax http://webmshare.com/play/Nro11

I have ffdshow installed. It doesn't show up in the list. When I browse for ffdshow.ax and select it, nothing happens.

Basically what the title says. I'm using this https://www.svp-team.com/wiki/SVP:MPC-HC guide to set up SVP for MPC but the ffdshow filter does not show up in the list. I uninstalled everything in the bundle then reinstalled everything in the bundle (except mpc because it's the 32-bit version) and it still doesn't show up.
