Windows Movie Maker will not import my files help!

I am trying to import a video from my camera to Windows Movie Maker but it keeps telling me 'invalid file format' how do i fix this?

Windows Movie Maker is old therefore newer file format do not work with it. Your only chioce is to convert the file before you import it in to WMM.

This website will do the convert for you, give it a try:
Media-Convert.com

Make sure to select "Windows Media Video (.wmv)"

Then import the converted video file in to WMM and you good to go!

You can always try Handbrake:

HandBrake: Open Source Video Transcoder
