I have some downloaded videos on my iphone that I can't access through iphoto or imovie or itunes because it's a download from a website through an app and it doesn't show up when i connect the iphone to the computer. Normally, I would just download it to iphoto like the videos shot with the phone and have it as a file on my computer. I would like to be able to view and hear the video on a larger screen. How can I connect the iphone (6) to either an imac or a tv so that I can view the video and listen to it on the larger device? Thanks for any advice.
