I've converted some DVD files into MPEG files, and now I have another dilemma. You see, I like to make movies using Movie Maker 2, but this one movie I converted is letterbox. I was wondering if there is a good program out there that will expand the video so that it fills a good portion of the screen, or at least match other clips. I'm willing to purchase, but if there are any free ones, then I'd like those too. The more suggestions you guys have, the better!
