opening TBS work in Macromedia Flash MX

I’m just wondering if or HOW you do if you want to open and edit/put music into your movie in Macromedia Flash MX from TBS?
I have a problem putting music thruu several scenes ansd not just one single scene, so I thought that Macromedia Flash MX would be better than TBS.
or do you have any other ideas?
is there any Video Editing Software where you can edit FLASH movies?
