Ummm... Literally inserted the dvd into the laptop tray and it didnt give you any "Auto-play" options???... THEN- 1. Start, computer, double-click dvd drive, should start playing. 2. Start, all programs, windows media center (or, nearly all pc manufactures have preinstalled media playing software, which you could use). 3. Download a dvd player app from the web (cnet).
