Video scroller changing from play to pause?

Hello all!

Building a custom skin for a flash video player but I do not want any play pause button. Instead I want the video scroller to play and pause on a click event.

Problem is I want to change the graphics on the scroller to show the user when the video is paused and being played?

I thought this would be easy but I have been tearing out me hair to get it too work.

I have attached the video player FLA file

Any help would be greatly appreciated!
