Oookay. This is the first time this has happened to me. iPad 2, iOS 8.1. iTunes 18.104.22.168. I connected it to my Win 7 PC to download some ringtones to the iPad. I get a "Oversize" error, and see a video that I previously deleted. I can't delete the movie from the iPad, and I had already removed it from iTunes. The "space" bar at the bottom of iTunes now shows everything as "Other" and I cannot back the iPad up to the PC. Reboots had restarts have been performed with no change of symptoms. Since everything is backed up to iCloud, I'm ready to wipe and reinstall.
