I am attempting to install digital copies of 3 films onto my iPad (for the sake of completeness: The A-Team, Captain America and Predators). These have all been loaded onto to my laptop previously (Captain America came as part of a triple play Blu-Ray package, the others are DVDs) and at least two have been on my iPod Touch. Due to my Macbook being about 6 years old, and thus lacking the necessary OS to interact with my iPad, I've been transferring music onto my iPad using mostly my father's relatively new iMac. I've encountered no problems that I've not been able to overcome until I attempted to transfer the digital copies for the three films mentioned above onto my iPad via the aforementioned iMac. I had no problems loading all three films onto the iMac using the redeem codes provided and all play in iTunes on that machine. Predators has transferred over to my iPad without a problem. It is playing also. Irritatingly however the other two films are not transferring and I'm receiving a notice on the iPad screen stating: 'iTunes Sync. 2 items could not be synced. See iTunes for more information.' No such information is visible in iTunes on either the iMac or the iPad. Does anybody have any idea what the problem could be? Thanks.
