iTunes Version: 10.0 (67) Devices: iPhone 3G 8GB (fw: 3.1.2) & iPad 3G 32GB (fw: 3.2.1) MacBook Pro 13": OS X 10.6.4 I tried researching this problem on my own but could not find anything to help solve it. So, every time I sync my iPhone or iPad, iTunes will re-sync all the songs to the devices even though I have not modified them. Each of the devices are not being synced from my main Library; I have created a playlist for each device (Library is too big to store on either device). Under "Summary options" I have selected "only sync checked songs and videos" and under each device I have the designated playlist checked in the "Music" tab. Also, in the same "Music" tab I have selected "sync selected playlists, artists, albums, and genres" but yet for some reason the audio is wiped out then re-synced each time I sync now. Is anyone else experiencing this same problem? Thank you for your help.
