Basic question about scroller tutorial

Hello Folks,
Done lots of reading here, but now I have a question.
I followed this tutorial on making an infinite scroller:
http://www.kirupa.com/developer/mx/infinite.htm
and was wondering if there was a way to limit the animation to when the mouse moves into the boundary of the mc.
I create the movie as outlined in tutorial, I publish, and load .swf into a blank mc holder in main movie. I would prefer if the scroller was only activated if 1.) the mouse was on the scrolling images/buttons mc itself, or 2.) at least within the confines of the clip it was created in, or loaded into.
Is it possible to add a couple of new lines of script to achieve this?
Any help would be greatly appreciated
Please keep in mind I ain’t got no skills here, so I need it sorta spelled out if you know what I mean.
Thanks in advance!
