ulead video studio, I was using that many years ago but I remember it was quite simple and final effect was pretty good. But like I said it was a few years ago maybe now you can find a lot more better programs than that . But try maybe you will like it
Since you don't wanna use movie maker I'd recommend sony vegas although it's not that simple but it's the only 1 I know XD Maybe Premiere is easier. If you have a mac my any chance you can use iMovie it's really simple and a good program but it's only for mac..
