Ok so I upgraded to the newest iTunes program and ticked the little box for prefer 1080p. How do I go about upgrading my tv shows that they now offer in 1080p? I understand not everything is 1080p, but on the stuff that they do offer in 1080p and I have already purchased how do I get it to download the file. I tried googling it, but couldn't find the answer or maybe was searching under the wrong key words. Thanks for any help.
