Here's the deal: I really want to be able to put videos and music on the hard drive of an Apple TV without keeping them on the hard drive of my iMac. I understand that currently I cannot do this because every time I sync my Apple TV to my iMac, all the music and videos I deleted off my hard drive on my iMac will delete from the hard drive on my Apple TV as well. Here's my plan: I am about to purchase Time Capsule. Could I use it (or any other external hard drive for that matter) to stream my music and videos to my iMac and then copy them to the hard drive on my Apple TV (or for that matter, stream them)? This way I can save the space on my iMac AND put all the videos that Time Capsule can handle on my Apple TV? One step further: If I wanted to create another account on my iMac and solely use it for Apple TV, is that possible? That way I could have my "regular" iTunes library on my normal administrator account that I update my iPods and iPhone with, listen to, etc. and then my "Apple TV" iTunes library on my "Apple TV" account that I update my Apple TV with. Would I be able to stream from iTunes on my "Apple TV" account even when my "Normal" account is the one that's active? One last bonus question: how well do videos/music stream from your Macs to your Apple TVs? Well enough to not have to worry about putting much on the Apple TV hard drive? I know this is a bit of a workaround, but I'm quickly filling up the internal hard drive of my iMac, but really want to store (or stream) a huge amount of video/music to my Apple TV. If someone can confirm that I can do all of this, I'm ordering my Apple TV this evening! Thanks guys and girls---you really are the most knowledgeable Apple people out there! I appreciate all the help!
