How do I combine a youtube video into one movie?

Question by Laura D: How do I combine a youtube video into one movie?
I have the parts of my youtube movie downloaded in mpeg4 files. How do I combine it into one movie to view it, instead of a skip everytime it goes to the next part? I am looking for a freeware program if there is a good easy one. Will someone make some suggestions?
I just realized that I have Movie maker, but it doesn’t seem to except mpeg4 format, so do I convert them to something else, if so what? And how can I make a smooth transition out of it?
