Dell Cineplayer

I no longer have Dells Cineplayer on my Hard Drive, because I had to reinstall Windows XP a while ago. I tried to play a DVD in my computer, but it didn't work.. when I did some research, I found that I need Dells CinePlayer..(Sonic). I used to be able to pop in a DVD, and right away there would be a screen asking if I wanted to play the CD.. where can I get a copy of this software?? Do I have to contact Dell support? (Which I am doing right now) I was thinking they would ship me a CD or something.. I do not have a copy of it anywhere.
