403837 Flash player autoscroll

need a AS3 expert to fix my flash MP3 player autoscroll. see the player here - [login to view URL] now here is a perfect working example of a mp3 player with autoscroll [login to view URL] As you can see from that above example, Autoscroll should be fast when hovering over the top and bottom of the playlist. Then the autoscroll should slow down (an ultimately stop) when hovering over to the middle of the playlist. I will provide the source file required for this project (flash CS4 source files)
