Instructions
Turn the PS3 on. If the AVI you want to play is stored on a USB flash drive, connect the flash drive to either of the USB ports on the front of the PS3.
Scroll to the "Video" icon on the PS3 main menu, referred to as the XMB. A thumbnail list of all the videos on the PS3's hard drive is displayed.
Select the AVI video you want to play and press the "X" button. Press the "R2" and "L2" buttons to rewind and fast forward, respectively. Press the "Square" button to return to the XMB and press the "Pause" button to pause playback.
