Just upgraded to Quicktime Pro. After exporting a movie for web (after saving as self-contained file), I can open the ReadMe.html file and play the movie if I access the page via the file system (by using File/Open in my browser). But I cannot the movie to play if I access the page via a URL (either on my localhost or on our production server). In Firefox and Chrome the player crashes. In IE, the browser keeps wanting to install the QT plugin but never will admit that the plugin is installed. Any suggestions? Thanks!
