The DCMedia player can be closed on Windows players by doing the following:
- Plug a keyboard into the player
- Press the escape key (you may need to press alt+tab a couple of times to make sure the player has focus)
- When the player quits, you'll be taken to the desktop and will see a window called DS Network Manager Agent
- Uncheck the Restart DC Media Player if not running checkbox at the bottom of the DS Network Manager Agent
