How do I ign a DVD to play on a specific application?

I had to have a new hard drive put into a Dell XPS200 that I bought less than a year ago & for some reason the tech that Dell sent did not install the "Cyberlink's PowerDVD " on here so now when I tried to play a DVD it automatically tried to launch it with WMP. My question is HOW can I pick something else to Open (play) the DVD with? When I go to the drive that the DVD is in I get "open" option plus all the other normal stuff you get when you right click but there is NO "open WITH" option. Thanks for any ideas
