If CD and DVD drives have IDE connector, then there are 40 pins, not 16. I'm sure Carlito ment well, but I'm just saing this so you wouldnt think where is 16 pin connector.
Another thing, when you take out CD, make sure you check position of jumper on it' back. See if it is set as MA (master), SL (slave), or CS (cable select), and then set the same on DVD.
Since you said it is DVD RW, then you most probable need some burning software as well as DVD player software.
