add your PS3 compatible-video to a PS3 supported external device and connect it with PS3.
PlayStation 3 supports so comprehensive external devices including Video iPod, Sony Memory Stick, CF Card, SD Card, Mini SD Card, Hard Disk and USB Flash Drive. It has a Memory Stick Card slot, a SD & Mini SD Card Slot and a CF Card Slot.

PS3 would automatically detect the device and display it in the “Video” menu on PS3 system interface as bellow:
Select “Memory Stick” and click 
button on PS3 controller, your videos in the “VIDEO” folder in your Memory Stick will be displayed.
Note: If the videos on your Memory Stick and other external devices are not in “VIDEO” folder will be not detected and displayed by PS3. However, you could find them by yourself: you could select your device and click button, then click “display all”. All folders and PS3 compatible-video files would be displayed.
If your device is Video iPod, hard disk or flash memory, you can connect it to PlayStation 3 by USB port. That’s to say other operations are the same as the case of memory card.
