This literally took me forever to find out. I formatted my SD card on my Mac and then popped it into my GF3. It then complained "THIS CARD IS NOT FORMATTED WITH THIS CAMERA AND NOT SUITABLE FOR MOVIE RECORDING". Looking through the menus and through the manual came up with nothing. Extensive Google searching later and it turns out that you need to have "Intelligent Auto Mode" turned OFF - that's the button with the blue light. Only then will extra menu items show up in in the settings screen.
