I also have minor issues when syncing my iPod 4G (20GB) with MC12 :
- when I click "handheld device" in the action window, MC12 detects two devices, a generic "Apple iPod 4G" (or something close) and my iPod as i named it "iRaf".
- I'm often (almost always...) obliged to sync it several times before MC12 finds no difference between the iPod and the local DB. I have to sync, then re-check sync (MC finds files to sync it had not detected before the first sync) , then sync again, etc., rarely more than two or three times... The differences are generally rating updates.
I never had this problem on MC11, but I didn't use song rating at all. If you want further information, I can do more testing...
Thanks in advance !
