A really good video editing program is Ulead VideoStudio 11 Plus. It has really helped me. I have used tons of different video editing software, and by far this is the easiest for me to use and very time and cost efficient. Oh Oh, almost forgot, they offer a free trial on their site.

You can easily get this off eBay for around $50. That is a great price for what this is.
Hope that helps.
