How do you make a video?

I have Street Fighter Alpha the movie on dvd. I have used Windows Movie Maker in the past to make a video that only has pictures. Windows Media Player is unable to rip the movie to my computer, and Windows Movie Maker cannot open it.
I first have to have it on my computer, desktop, then it has to be WMA file so I can make the video using Windows Movie Maker. I am going to cut certain parts of the movie to make a video that will last about four minutes long. How can I do all of this?
