I'm trying to get some clarification on something. I have some digital copies that I received from buying blu-ray disks. I just downloaded one and it saves the file locally to my computer. I have several of these that I'd like to get loaded into iTunes but I don't want them to hog up space on my computer. Is that the only way that I can watch them on my Apple TV or can these files be stored on the cloud? I only have 5 GB of space though so would that basically mean that I can only store 2 or so (they run about 1.7 gb each). I guess I'm just confused as to the relationship between files that you've downloaded elsewhere and have stored locally on your computer to stream to Apple TV and files that you've purchased from iTunes and wish to stream to your Apple TV. Can someone explain?
