I have mp4 videos that will not transfer to my ipod. i have attempted to "create an ipod version" - that allows the file to be transferred to the ipod but when playing the video it is simply a white screen (however, the audio will play). i have double checked the settings to make sure i transfer all videos in the library, but for some reason these mp4 videos won't transfer. they were all taken with my new camera (Samsung TL220). any suggestions?
