We use Adobe Presenter (formerly Macromedia Breeze) to do this. It produces Flash animations which helps overcome the problems you are experiencing, but isn't cheap. You can see details of our approach and the output at http://www.le.ac.uk/thebridge/projects/building-induction- bridges.html Another much cheaper commercial product is SMIRK (http://smirk.herts.ac.uk/).
