I am VERY frustrated. A couple of days ago, I updated to the latest software (I have iPad 1), and now most of my videos/ movie files won't copy across from iTunes to the iPad. Many of those that were already on the IPad have been removed, too (still there in iTunes). The audio files are copying across fine. This is seriously denting my enjoyment. Does anyone have any advice? If it's a software glitch, I hope an update will arrive very, very soon.
