Windows Movie Maker files

Wayne called about converting (mov) files for Windows Movie Maker...

Per http://support.microsoft.com/kb/308464
File formats supported by Windows Movie Maker in Windows XP
Supported formats for importing content
• Video files: .asf, .avi, .wmv

"Although you can play a file in Microsoft Windows Media Player, you may not be able to import the file into Windows Movie Maker even though this article lists that kind of file..."

Anyone have a (free) program to recommend?...
