Blaze Media Pro is an alright program. You could also try Sony Vegas, only problem is that the 30 day trial doesn't allow you to open or work with MPEG files.
i used to use wondows movie maker, but it had a habit of doing really fustrating things, i know alot of people had the same problems. now i use adobe premier pro 2, its such a good program and produces some really professional looking videos.
