I recorded a video in Movie Maker, through the webcam on my computer. When I ended the video, I saved it to my computer as a WMV file. When I try to open the video it says that the file type isn't supported. In Movie Maker, there is a yellow triangle with an exclamation point over the video. Can anyone help me figure out how to play the video? I need to save it in order to compress it and submit it for school.
