Pause Flash Via JavaScript

Hello All! On this page [login to view URL] I have a Flash game. Once a user clicks 'play' the sound wont stop. I need to be able to have the game either stop playing sound, or to stop completely . I need the Flash game to pause/stop when a user moves their mouse more than say 100px away from the flash game. The game can continue if they move back into the box/game I do not have access to the FLA file. This needs to be done via Javascript. I am open to suggestions on how to tackle this. Please explain via PM what the best option would be, and make your bid. Budget is very low, so hopefully it is an easy fix. Cheers Chris
