Why can I upload to Mediashare using Windows Movie Maker in Vista or Windows 7?
Microsoft removed the “publish to web” option in Movie Maker 6, beginning with the release of Windows Vista. Using Windows Movie Maker in Vista, you can simply create your video as desired, save it on your local PC, login to Mediashare via your web browser, and choose the UPLOAD menu item to upload it via our standard browser based method. Alternatively, you can use Windows Live Movie Maker, utilizing the Mediashare plug-in.
