Hi, does anyone have any idea what could be causing this knocking sound when viewing the camera and playback? The cam is running firmware 5.1 and i just noticed i cannot successfully format the memory card. I'm going to update the firmware and buy a new card in a day or two.
Could it be interference from an electrical device?
