Modifying the Apple TV 4th Gen
I didn't do my research before buying my Apple TV 4th Gen. I have 2 Apple TV 1st Gens (160Gb HD) whose hard drives finally quit, so I bought the 4th Gen to replace them without confirming that the 64Gb could natively host media files without having to stream from my macbook pro, which is the feature I most want out of my Apple TV. Obviously, I know now that the Apple TV 4th Gen is designed not to do this.
I had my Apple TV 1st Gen connected to my home theater receiver which, in turn, is connected to a 6 zone speaker selector. The speaker selector distributes sound to 5 zones inside my house, and 1 zone outside in my backyard. I use Apple Remote App on my iPhone 6S to scroll through my music files which are natively stored on my Apple TV 1st Gen to play throughout my house. That way, I don't have to have my TV turned on and be standing right in front of it to see where I'm navigating on my Apple TV.
Here's what I want to be able to modify the Apple TV 4th Gen to do:
1. Not have my laptop on and running iTunes (in other words no streaming either from the cloud or computer)
2. Be able to scroll through playlists, smart lists, and individual artists albums on the Apple Remote App on my iPhone while I'm outside in the backyard, or in an area of my house away from my TV, where the Apple TV is located. In other words, force the 4th Gen to store music files on it's 64 Gb hard drive (I have ~20 Gb of music files).
I have read about apps that enable the Apple TV 4th Gen to store movies/tv shows natively on the 4th Gen. I presume these apps would also enable music files to be stored as well, although every thread I have read about the various apps (VLC, Boxee, Plex, Infuse). Although descriptions are vague, so I'm not clear whether they actually force storage on the Apple TV itself, or do they store on their server instead, which defeats my purpose? I don't want to pay rent on my media files to store them in the cloud, nor do I want to waste my time having to turn on my computer to run iTunes (or use the extra energy having my computer running to accomplish something that the Apple TV did so perfectly 4 generations ago).
Which of these apps, if any, accomplish my goal to force the Apple TV 4th Gen to store my music files on its hard drive?
We have the technology! We can rebuild it! Can't we?
Thank you for your help.
