Hello, all. I took some movies the other day with the Vision 2 camera, however, when I try to download the movies onto the computer, a message comes up indicating that the mp4 file is not recignized and cannot be played. This is on Windows Media Player, Real Player, Windows Movie Maker, etc. I have downloaded all of the updates. This is the first time this has happen, as in the past I have had no problem. Any help would be appreciated Thanks Chuck.
