Adobe Air - Help displaying video

I have an application on ADOBE AIR (JavaScript and jquery based) that plays various video in mov and flv format stored locally. Once one finish, the next start in the same position. I no have problem with It. The problem I have is that once the video is finished it doesn’t release the memory used, so in 30/40 mins the application crashed for full memory problem. I need someone that fix my script. Attached is exactly the code where the problem is. To run it you must use "ADL" command. You can run it an see how much time will take you so you can quote me exactly.
