I quit windows movie maker long time ago. I'm not an expert either. I just do some editing on family videos. So I googled something. CyberLink PowerDirector 14 Deluxe and Filmora are handy. Sometimes I use wondershare an wonderfox. They can do not only movie editing but video conversion. The latter are handy. But I'll let you to judge. I just enjoy making family movies and do some conversion from avi to mpg or ds to mp4. After that I can upload it to YouTube.
