Xml thumbnail scroller problem on external swf

I have a external swf file of the kirupa xml thumbnail gallery. the first problem i had is the thumbnail scroller didnt work. ive been struggling to fix this problem, for a few hours now. ive been googling this and found solutions that i had to change _root. to _level0 , _parent, and _root.container these kinda works but the next big problem i have now is that it scrolls but it keeps shaking left and right constantly and tis really bugging me. any solution to this? thx
