I have a Macbook Pro and a desktop PC with iTunes installed on each with the same account. However, my iTunes purchases are not reflected the same on each computer. For example, my Macbook has two tv seasons of The Wire that does not appear on my PC iTunes. Also, there are a number of apps on my PC that I don't have on my Mac notebook. This is especially annoying as I sync my iPhone 4 most frequently with my desktop. Any insight or suggestions on this? Appreciate your help!
