I just purchased a new 30gb ipod video. It seems to have a modest glitch in it. I am playing a video like Lost on it and I attempt to switch back to an audio book and the audio books sound is unclear and distorted. It seems like the video is almost still playing in the background. I have to go to the end of the video before I can clearly play the audio book. Does amyone think there is a problem with it and I should return it? Thanks
