Hi can you help please? I borrowed my daughters Panasonic DMC-TZ7 digital camera in place of my Casio Exilim camera (far better zoom and sharper pictures) to take on holiday to the Norwegian Fjords but now cannot download the short videos I took to either my PC or directly to my I Pad 1. When I returned the camera sim card used in the Panasonic camera to the Casio camera the videos have completely disappeared and cannot be played on this camera. Any idea why please and how do I rectify? Kind regards. Murphy150.
