I just bought an iPad Air, a Lightning to HDMI adapter and an Apple TV. I'm a new Apple user and have never used any Apple product before. I was told that I could use Apple TV to play movies wireless. I went to Best Buy and the CSR told me about the Lightning adapter, he said just hook it up to my TV and I can play movies that way, he said I would need to download a video player from iTunes like VLC, etc. How do I go about doing all this? I have a bunch of .mkv files that I want to watch. How to I get these onto the iPad and is there an app to play them once I have Lightning adapter hooked up? I guess I can return Apple TV also.
