Huh? PrintScreen by default doesnt work. If you are talking about WMP then the video acceleration from the Performance tab of options Menu needs to be reduced to none, to make the printscreen and ctrl+v method to work. Have a look at this page.
My bad. I have to admit, i never actually tried printscreen-copy-paste with a video. Just assumed it would work.
I apologize for the misguidance, abhijitroy. You know, sometimes experience makes you say things that turn out to be quite different from what you expect

By the way, nice research there, Sourabh.
