From the developer:
StrongRip is a simple application to back up or rip your DVD discs to popular video formats, so that you can play the media files on your favorite devices. The program allows you to extract audio from DVDs, convert DVD by title, choose subtitle and audio track, trim the video length, and add the output file to iTunes automatically.
