I redeemed a movie in iTunes on my Mac and choose download later. Later, I choose
Store > Check for Available Downloads… and it reported that all of my stuff has already been downloaded. So where do I go to get my movie onto my Mac?
Ok, the problem here is that I have actually been looking for something in the iTunes application UI to do this. Rather, the solution seems to be in the web pages served by the iTunes Store.
You must have the iTunes11!
Then use the "Check for Unfinished Downloads" under Store Tab at the bottom of the pop up.
Click on your Purchases tab.
