Things You'll Need
Instructions
Transfer your AVI files from the computer to a removable storage device compatible with the PlayStation 3. You can use either a USB drive, portable hard drive or high-density memory stick.
Connect the removable media to your PlayStation 3. If you are using a USB stick or removable hard drive, connect it to one of the four USB ports on the front of the PlayStation 3. If you are using an SD card, insert it into one of the PlayStation 3&'s SD card slots on the front of the console.
Turn the PS3 on and then scroll to the "Video" icon on the cross media bar (XMB.) Then scroll down to the device that contains your video files. Select it and press the triangle button. Select "Show files" from the menu.
Scroll down to the AVI movie you want to play and then press "X" to begin playback. If you want to exit the video playback utility at any time, press the circle button.
