When I put CD's into my drive they play fine and it pops up on the desktop like any other CD I put in it. When I put in a DVD video, it automatically opens the DVD player and when I click play it says "Supported Disc Not Avaliable". Also There is no way for me to eject the disc since it doesnt show up anywhere except for shutting down, and holding the mouse button in when it restarts. Do I need some sort of special video thing to play DVD's?
