You have not mentioned the model of the digicam you are using. Can you see the movie files in your camera? I think you need to seek help from an expert. If you wish you can visit
http://www.supportonclick.com. The staffs over there can provide you proper advice. They are quite helpful and extremely skilled in performing a lot of difficult jobs. They helped me a lot while I was having a lot of trouble with my canon digicam few days ago and now it is working fine. I hope they will also be able to help you out of this problem.
