I'm a novice looking for some help. I would like to use AppleTV to play media without running through Itunes on a separate computer. It seems that the only way to do this is to synch the media to the AppleTV itself. My problem is that I have way more media than the Apple TV HD can handle. I know you can crack the case and upgrade the HD in the machine but the largest HD I've seen for this purpose is 320GB which still isn't enough storage. So I see a few potential solutions/have a few questions: 1) Is there a bigger HD (at least 1TB) on the market that can be put into an AppleTV? 2) If not, is there a way to attach an external HD via the AppleTV's USB port and use that at the machine's HD and therefor not need to run through a separate computer with itunes? 3) Right now my media is stored on a network attached storage device (not running windows or apple os). Can I put software onto that device to have it act as the Itunes device? Thanks for any help/advice!
