movies download to iPad 3rd Gen.

This has actually happened to me several time before. I experienced an issue while transferring two rental movie to my iPad 3rd Gen. Halfway through the download of the second movie, I received this message on my iMac, "Download not complete connection timed out.

What I have now is a fully loaded movie, and the iTunes on my iMac shows two movie icons on the iPad. however only one of the two movies shows on the iPad. The first move has two buttons associated with it (MOVE) or (DELETE). The other move only shows one icon (DELETE). Which means I can't even move the the second movie back to the iMac. If I choose delete, then I have to re-rent the movie. The other issue is the second movie is actually is taking space up on the iPad, so I can't load another movie, because of other data on the iPad.

Anyone have any ideas?
