Media player error

I installed some new codecs to render a video, and it works in a DivX player. Now when I play ANY .avi (havne't tested other types) in Media Player Classic. I get this:




Any help?

The whole error:

I still get the same error. Videos work, they just don't show picture; only sound.

Uhh, there were about five things that I installed, I forget what exactly though..

I found a way to view all installed codecs, if that helps?

How do I uninstall them?
