SWF Issues

Hi All,

I'm having some issues with a swf, it was created in house in AS3 (but only contains a stop command), when the swf is played outside of Storyline the animation and audio are perfectly synced, but after inserting the file into Storyline they somehow un-sync. What is a little odd is if I preview the swf on the slide it works perfectly just not in the preview mode or when I publish. I have tried various options but nothing seems to work, triggers, automatic playing, using the controls etc.

The swf is attached if anyone can help.

Thanks
