Hi, I am trying to play a dvd on my laptop. I have windows 7. The whole errror message reads; 'This file does not have a program associated with it for performing this action. Please install a program, or if one is already installed, please create an association in the default control panel.' So I went to the control panel just to see what I could see..In the media section under the diff categories 'play music', 'play dvd', etc it has drop downs that says choose default. I dont know if that has anything to do with it, but I tried choosing diff programs, media player, realplayer, with no avail.. Please help!!
