Unfortunately, the Media Player Plugin doesn't have the ability to take a screenshot. However, you can perform this action without any additional tool using the in-built functions of the OS. To do this, you need to press the Print Screen key from the keyboard anytime you want to take a screenshot. The picture taken will be saved in the clipboard, and you can use Paint tool from Start > All programs > Accessories > Paint to modify and save it. Use the Paste option from the Paint program or simply press Ctrl + V key combination to paste the picture.
