"The File Format Is Invalid" I took a video using the phone itself, and when I tried to play it via Start>My Pictures & Videos> File name 041 the phone displays a message "The file format is invalid". The properties for the file as follows: name=041; File Type= 3GP Video; Dimensions=N/A; File Size=18MB; Date Created=09/05/2008; Protected=No. I know it is a large file, however I figure that if I recorded the file with the device itself it would be able to replay it? Has anyone had this issue as well? I searched for this issue in the forum and found nothing that related so I apologize if this has been solved before.
