Hi,
Windows Media Player 10 has a built-in screenshot feature for MPEG and MPEG2 content which can be used by just pressing “CTRL+I” together during playback.
If you want shots of the whole screen and Media Player user interface, I’d suggest you to turn down the video acceleration used to create the picture.
Follow these steps:
a. Open Windows Media Player (WMP).
b. Click “Tools” > “Options” > “Performance.”
c. On the “Performance” tab, reduce the video acceleration to none.
d. Click “OK” and exit WMP.
Now, open the video file of which you want to capture a screenshot, press ALT and the Print Screen key to copy an image of media player to the clipboard. Once copied, open Paint and save the picture.
