I have a Casio Exilim EX-Z8 camera and took some short videos when I was on holiday. This plays back great on the camera, but when I downloaded on to my PC it will not play. It is supposed to play in “Quick Time” I have the latest version and all that I get is a green screen and broken sound, other Quick Time movies play OK. I have been on to Casio support several times and they contacted Japan, which was not much help and asked a few questions. In all they said they did not have an answer, goodbye. So I have lost my holiday video shots.
