Preloading swf containing DataSet & xmlConnector

I’m creating a flash web application for a carpet company that users can build a floor plan, save, load, blah blah. It’s database driven to load the carpet swatches and to save the layout to sql, using the xml connector.

Problem: xmlConnector and DataSet components need to be on the first frame of the movie clip to work. Can’t use loader component on another movie and load the swf into that (even using lockroot) because flash still wants any components used on the first frame of that movie…

How, please, if anyone knows can I preload this movie?
