I recently started using iMovie '09, and one thing I'm having trouble doing is making transitions work when also using picture-in-picture. It seems that once picture-in-picture is applied, the transitions don't appear. The only reason I'm using picture-in-picture is to overlay a PNG watermark on top of the video, which I can't do like in iMovie '08, which was just a simple drag and drop. Any ideas how to overlay a watermark more easily, or how to make transitions work while using picture-in-picture? Thanks!
