I have converted many file types for iMovie 11 using Won tube free video converter. I have found it easy to use and it converts most codecs. Most of all download is free. It files the result in its own file under Won tube. Just drag them into iTunes as long as they are converted to mp4. if that is where you want them ultimately for iMovie.
