All the Software DVD Players for Windows i know have
functions to save the current image. Mostly these
buttons are hidden in advanced sections of the
player. I'm using WinDVD - there you have to press
the button with the left arrow to access the advanced
option and there's a button with a camera. The
images are normally saved to 'personal files' (i
don't know if this is correct because i'm using a
german windows. there's a subfolder for images and
there are the images.
another way is just to make a search with the
windows search for the most recent files after
making the screenshot.
The print key can make problems with DVD Players
beacuse they are using overlay that is hard to
capture.
