hi Gamal,
yes, i meant they disappeared from the iPad's iPod music and video, we purchased a few movies and lots of songs. i think it is an itunes issue perhaps. i authorize and deauthorize on a laptop loaner and i still don't see any of the 500 songs/movies i purchased.
i do, however, have all of them in a main PC in Los Angeles that i synched with the Ipad and my iPod and iPhone last week.
thanks
