Compositing Digital Juice animations in Vegas

Hi Guys n' Gals,
Can someone please point me in the direction of any tutorials or discussions on how best to implement the Digital Juice Editor's toolkit animations? I have bought one of their mega libraries for a project I'm doing, but am having problems with the 'parent'/'child' relationships involving the backgrounds, mattes and video footage. Just ignorance on my part I'm afraid. It's the first time I am trying to create a composite in Vegas, and alas the manuals aren't helping much.
Many thanks,

Bruce Quayle
