So flash is trying to pull in the flv file. It doesn't embed it into the swf like you think it does. In the component parameters under contentPath, change that path to be relative to where the .swf is at on the server and it should work. I've tested this theory by giving it a contentPath that isn't relative to the swf file and it gives me the same behavior as you are seeing. Once I gave it a path relative to the swf file it started working. Right now where in relation to the fla file is your flv file?
