Final Cut Express is limited to working with DV source material, hence the title "Express". I moved from iMovie to FCE. When I finally decided that I didn't want any limitations imposed on me, I ponied up for Final Cut Pro and have been happy ever since. Seeing as how you already have FCE, I'd recommend this training dvd to get used to the Final Cut workflow. That dvd is for FCE 1.0 but would be more than good enough to get you comfortable with the interface. The FCP and FCE interfaces are practically indentical. Good luck.
