HELP!!! How to edit videos wit windows movie maker but the vids not compatible?

Answer 1

Open Movie Maker> Click Tools> Options> General tab> check "Download codecs automatically"> click OK...

Try loading the file again.

If that fails, try locating a file converter and convert the video file to something that Movie Maker will handle.

Here's one:
