I'm trying to watch a DVD on my laptop, which I do often, but something is not working. I've watched this same movie recently on it though, so I think it must be the computer. You know how a window with a choice of "What would you like to do with this disc?" pops up when you insert a DVD/CD? It's not popping up now, and I already tried re-inserting the DVD. I've looked under all my program files, and can't find the name of the movie-player that I usually use. It's just the basic one that comes with Dell computers... anyone know how I can start it up/find it?
