Anyone one my flist know how to get WMM to recognize the new codecs I've installed? I've restarted my computer 3 times since I installed them, and I can play the clips using WMP, but WMM is still only showing AVI Decompresser Ver 6.6.6 (No, I'm not making that up) on the compatibility tab, and the imported clips won't play at all.

According to the About tab I'm using Windows Movie Maker 6.0.6.
