How do I make my dvd r/rw cd r/rw work even after I have downloaded the drivers? - dvd r rw

I have a Dell Latitude upgrade my PC with a DVD-R / RW CD R / RW combo module. Also an upgrade to Windows 2000 and Windows Media Player 9 Series. The problem is that after my system recognize the device remains to be done. I was told that I need a decoder of some kind. I tried Media Player downloads and could not find, it seemed everything that is reasonable. Can you help me, what they need help on my DVD-R / RW CD R / RW, possibly combined with the player window 9 Series for Windows 2000?
