I think you may be thinking of the DVD called "The Secret" - it is also in book form.
Rick (our resident hypnotherapist) had suggested it to me and I got it and watched it and it was fabulous.
The basis of the movie/book is that you get what you ask for from the universe. Example, if you are in pain and think about the pain, the pain will get worse. If you keep positive thoughts it gets better. I did order my dvd on Amazon.
As an aside, when I get very depressed which I was recently, I tend to not be able to get out of my own sh**. This video helped. I find when I think of the positive things always get better and my depression is improving
