I have an original ATV and my only complaint is the power use and heat and sound it gives off. A friend lent me a ATV2 to try. I've hooked it up and configured it for sharing, but it seems it's missing much more content than I though it would. With the original ATV, I configured iTunes on my computer to "know" about the ATV. When I went to the Movies menu, all of the content on my Mac is there. This does not appear to be the same on the ATV2 Is this function simply no longer supported? Or am I forgetting to do some additional setup?
