iPod Classic video 同步問題

If you choose to synchronize your iPod with your itunes, then what you said in the first question will happen. That's a way that you may take it as a reference, which I am doing this as well - just synchronize for the first time when you use it and then turn off the synchronization. You will thereafter have to drop the songs to your iPod manually, but then you will not lose anything if you decide to remove some of the songs in your hard disk.
