How to put youtube videos into movie maker?

Normally, the downloader you use to get the YouTube videos onto your computer has settings for the file type to be saved. Check the downloader and see if you can set the kind of file type you want the downloaded files converted to. Redownload the file as an WMV file or use a converter to change the downloaded file into a WMV file type. If you're downloading a commercial song/music and plan on using it in a Movie Maker creation that you'll later upload to YouTube, be warned that YouTube shuts off (mutes) the audio of videos that use copyrighted material.

First, if you want this legally contact the owner of the youtube video and ask him to give you his video through email and if movie maker doesn't support it , you can easily convert using some converting programs like mpeg stream clip And then you put it into movie maker however , if you want to do it legally (which i dont advice you at all , you can find some sites which you can use to download videos from youtube and convert them to mp3 and save them to your computer But dont take the illegal away ... you will get into trouble in the future :D
