QuickTime XiphQt not working

Hi,

As you can see above I have XiphQT installed into my QuickTime folder and yes, this is my library. Whenever I go to play .ogg files on Safari it won't let me because it says I don't have XiphQT installed. Where it says folder in the above image I think it should say component because I watched a video on how to install and it said component on the video.

If you have any way to fix that it would be great! Thanks
