I just downloaded ER one hour retrospective from Itunes in HD. When I try to play it back it will not allow it saying I need a HDCP connection. I thought there might have been something specific about the program so I tried to play a previous Itunes HD Dexter program and got the same warning. I never saw this before when playing the Dexter program in what I thought was HD. Is there a new policy in effect at Apple and if so why no warning? Any insight from the forum would be appreciated. By the way I am using a mac pro 2.66 with a Dell 3007WFP monitor.
