What is a DVD decoder and how do i get it? - how do i find out what series my nvidia is

I've formatted my laptop yesterday, helped me do my friend.

Now I can not install the VGA and VGA drivers from NVIDIA Acer CD, because "the system will find the path specified.

Well, when I tried to play DVDs without the screen and only the audio is with a black screen.
