basically it's nothing more than a movie with the window turned off, and interactive sprites to replace all the controls that the window used to have (play, pause, volume, etc). In general you need some moderately expensive software to author such interactivity* (LiveStage Pro, Flash, etc)
*but writing this gave me an idea that it might be added to a certain free utility I've been writing. But since I personally wouldn't use such a feature, it won't be at the top of the list...but if you know your C, these things wouldn't be hard at all to implement yourself...look for WiredSpriteUtilities.c on the sample code page......
