View pictures on a dvd-r

Hello,

Could someone please tell me how I view my pictures from a dvd-r from my laptop? I have inserted a dvd-r into the dvd drive, but nothing happens. I thought that a window would open with the option to view, file, save etc., but nothing at all happens. If I go to my computer, it only shows the Acer and Data icons of my hard drive. It seems to think that there isn't a disc in the drive, when in actual fact there is! Do I need a special programme to run the dvd?

Any help greatly appreciated, as I really want to view my daughters wedding pics! Thanks.
