I couldn’t import music or video (avi). I downloaded the FFDShow that Whee mentioned. You will have to extract it from a zip folder. I ran the program and let it choose all the settings by default. Now I can import my music and videos. TY Whee!

"The file C:\Fraps\Movies\codsp 2012-12-17 20-34-55.avi cannot be imported because the codec required to play the file is not installed on your computer. If you have already tried to download and install the codec, close and restart Windows Movie Maker, and then try to import the file again."
