I have purchase an iTunes TV show and it is downloaded on my MacBookPro. How do I watch it on PTV2? I have homesharing ON on both computer and ATV2. Thanks!
Go to Computers heading on TV menus, should see your library listed--select it. Once your library loads, select TV shows and you should see your show listed.
Also, I've been out of town since the last update so I'm not sure, but I believe you should be able to access anything you've purchased using your Apple ID under the TV shows heading on the TV home menu.
