Mac Mini wont eject a disc

My Mac Mini has taken a DVD and wont play or eject it. I have used the Keyboard Eject button, F12, the Eject button on my Mac Mini's dvd program and I dragged the Disc icon to the trash. Nothing has made this disc eject from my Mac Mini. When I tried to restart my Mac Mini while holding the mouse button down the computer Froze and now will freeze when ever I try to Shut it down. Anyone ever had this problem or know how to get it out? It is a standard CD.

Thanks In Advance!
