How can I convert a Real Player file into a file Windows Movie Maker can import?

I am trying to create a video with the .rmvb (Real Player) file I received from http://saiyanisland.com/

I had this same problem, you need to get a Video Converter. Then you can convert the .rmvb into .mp3, .mp4 or .wmp or whatever you need to import to Windows Movie Maker. There are some free ones out there, try Xilisoft if you don't have very big files to convert (you have to buy it to convert files over 5-7 minutes long I think).
