Things You'll Need
Instructions
Rent, purchase or borrow a movie on Blu-Ray. It does not matter what movie you get.
Turn on your PlayStation 3 and insert the Blu-ray disc. Make sure you don't have any other discs in the drive first or you will not be able to insert the movie.
Press the "PS" button in the center of your controller to turn it on, if you haven't already, and scroll to the left to reach the "Video" menu.
Scroll down until you reach the Blu-ray icon, and press "X" to select it. If your PlayStation 3's Blu-Ray player is working, it should read the disc and bring you to the Blu-ray's menu.
