My cacmorder has video files that r in the format .mov/.mp4 (H.264). Everytime I convert a .mov/.mp4 clip to a .avi, then import it to WMM, it says "Windows Movie Maker has encountered a problem and needs to close. We are sorry for the inconvenience."
Why does WMM crash when I import a .avi clip that was originally a .mov?! Plz help!!!

It was an 11 minute long clip of my video game btw. Resolution is 720 x 480, and it was recorded directly from the TV to the camcorder's LCD via an AV cable.
