My 30GB Classic only outputs stereo about 10% of the time. If I press down hard on my headphone plug, I get stereo. Is there either a way to switch my iPod or library to mono without reimporting? Or fix the iPod without sending it away? Also, why won't my Podcast Playlists sync in iTunes 9 with my iPod classic? The podcasts are there... just not in a playlist. I'd like to avoid buying a replacement Nano if I can. The battery is acceptable, it's just that darn mono playback that ruins my songs.
