a few minutes ago, i was watching a video on my ipod fine. as soon as i plugged it into my computer, it stopped recognizing them as mp4 video, and showed them up as mp3 music files, in itunes and the ipod. now when i play the videos in pod, it just plays the sound, not the video. in itunes, the little TV icon next to the video files doesnt show up no more, since it reads it as an mp3 file, but if i doubleclick on it, itll play. anyone know howto fix this?
