tow programes needed
 

1- a program can take a screenshot form video
2- a program can take a screenshot and save it automaticly .
it would be better if there is one program can do both instade of tow

I'm pretty within xine, there's a little button or menu option allowing to take a screenshot which is automatically saved to your home directory with a default name based on the date + time or something.

Thanks man .. but is there a way to prevent xine form showing the message after taking the screenshot ?
and for games is there another program ?

Check your keyboard for the printscreen button. Let your imaging program take it from there.
