1. Open Windows Media player. Click Tools -> Options -> click on the Performance tab -> then click Advanced

2. Make sure that “Use video mixing render” is checked and “Use overlays” is un-checked.

3. Save your options, play the movie with the Media Player, when you see the frame from the video you want to grab press the PrtScrn button.

4. Open Paint or any other image editor, open a new image file (Ctrl+N) then paste the screenshot (Ctrl+V). Save your image.
