To make a screendump of a DVD movie (or anything) go to Terminal and type: screencapture -ixP ~/Pictures/dvdshot.png After pressing the Return key, press the spacebar and you'll get a camera icon. Make sure the picture you'll take it from is the top window in front. Then press the mouse and you'll get a window where one can select the format to save the picture in. One can also choose a new name instead 'dvdshot'. Paul Moortgat
