Could I pause the dvd and save the image to my computer?

If you are viewing in full screen without any controls shown, pause, click on print screen, then go to Start-->Programs-->Accessories-->Paint and paste & Save as.... in whatever format you want... (Jpg, Png, Bmp.. etc..)

OR

Your DVD player software will definitely have some options to capture images. So check with your dvd player software's help.

Hope this helps!
