Using Screenflow or Snapz Pro X, these are not screenshots, theses are movies of screen actions. The output is a DV file, a movie. Screenshots are .JPG or .PNG files, they are snap shots or photos of the screen, no motion, just a picture. iMovie does not need to render a DV file (movie). iMovie does want to render screenshots, photos of the screen, .JPG or .PNG files. When iMovie asks to render before sending to iDVD, do not allow iMovie to do so, let the rendering occur in iDVD.

No, you are making movies of screen actions! :)
