Manually adding movies to iCloud.
Is there any legitimate way to add movies I've manually added to iTunes to the Cloud? I have movies in iTunes with the iCloud icon on them, where I can still watch them they just don't take up space on my computer. They also show up on my Apple TV so I can watch them there. What I want to do is have that same thing for some movies I haven't bought from iTunes but from somewhere else. Then I can remove the download but still have them available to stream.
Thanks,
Zac
