So I take the laptop apart. It's 4 years old, so the warranty's gone. And when I mean apart, I mean every single screw, nut, and whatever came off. And then, I put it back together. And now the DVD drive works again.
I have yet to try the card slot yet. (A slight crack in part of the plastic itself. Pushed it back into proper position.) Mainly because I don't know where I put that old B type wireless card. :P
