Hi,
Don't think Movie Maker is hard, much easier than most PC stuff out there, only one I've seen ( not used ) which is more intuitive is imovie for macs.
You could try any of the many pinnacle products out there but these just add more complexity and functions to that of Movie Maker.

Cheapest way is Movie Maker and burn the resulting avi to DVD using sothink, which is also free.
