I have a large (25MB) video file that was given to me. It’s a swf file that someone created from a quicktime movie. I can’t just use this swf file as it needs to fully load before playing. I have created a preloader that loads the external swf and shows a progress of the external swf file. However, the external swf file starts playing. I want to stop the external swf from playing until it fully loads.
