bit of a long shot here, but I figured I’d risk asking anyway and see if any cappers out there might be able to help! I have one movie in .mv4 format that I need to convert to .mp4 to screencap. the movie is, of course, from iTunes and thus needs the DRM removed. aside from paying $50 for a program to remove the DRM and convert the file format for one movie that cost me $8, what are my options? can anyone recommend a free converter?

thanks a bunch!
