Forgive me for asking a question that has probably been answered before, but I wasn't 100% clear when I read through the various threads on this board. Here's my situation and question. I have an rMBP, iPad (v1) and iPhone 4S. I have a Time Capsule. All of my media (MP3s, videos, photos) resides on an aging Windows PC connected to my HDTV. I would like to replace it with Apple TV (and say goodbye to Windows altogether), but only if I can do the following. Can I do the following? Can I hook up an external USB drive to the USB port on Time Capsule, store all my media (MP3s, videos, photos) on the drive, then somehow get it to play on the Apple TV, seemingly through either my rMBP, iPad or iPhone? It sounds like that's possible based on my reading, but like I said I'm not sure. If I can, how does that work in a practical sense? Does it go through my apple device (iPhone, for example) and then go to the ATV? Is there a drain on the phone/rMBP/iPad when I do this? Is there excessive lag doing this? I don't mind keeping one of these devices open if that's the requirement, I just want to know how it goes about doing its thing. I'm interested in the Airplay Mirroring feature with my rMBP and iPhone, but want to be able to play my media without having to mirror...and without having to store all that media on my MBP's internal hard drive. Thanks for any clarity you can provide.
