Hi. I've created a video comprised of a series of photos (like a slide show) and music. I clicked SAVE MOVIE and chose "Computer/Data" as the output and .avi as the File Format. It created a 27MB file and when I view it it's fine. I copied the .avi file to a folder on our network so others can view it. However, when they open it (on other computers) they hear the audio but there's no video. What did I do wrong? I tried it from another computer myself and got a "error downloading codec" message before the video began to play. Sure enough, there was NO VIDEO but the audio sounds fine.
