OK, I have converted some musicvideos (mpg) files to 3GP files and put them on the Card. When I play them on the pc they are fine. When I play them on the phone, the video is jerky and the sound plays fine, but the sound doesn't sync up with the video. I have used the recommended setting of QVGA Normal quality 15 fps Stereo for the 3GP_converter. I wonder what I could do so that the videos would play better? Thanks for any help.
