this trick works with MediaPlayer, try it out with your DVD program.

while in DVD playback, take the cursor up to the top right of the program's window and click (and hold) on any of the three buttons (minimize, maximise or close)

with the click held, hit the PrintScreen button.

you may have to try a few times- almost always works.


*EDIT*

whoops, i failed to notice that you already solved the problem. nevermind then!
