Thanks Kgun. I just read the other thread. This Sony vegas also converts video formats from one format to another. I spent a lot of time downloading many software to do just this. Windows Movie Maker will not open most video format. It will happily work with wmv format however. But once you get Vegas, you can throw out most of these converters.
It is a daunting task to create an acceptable result in Video. It uses lots of time, hard disk space and effort for starters like me.
