I use VLC Player here to play such things. I can't guess what play correctly is.
My iPhone 6+ videos play sideways after I move them to my Windows home pc> I plug iPhone into usb port, the dialogue box pops up asking if I want to access the phone, I say yes and move or copy the videos. I have asked 4 "Geniuses" so far and nobody knows how to get videos to play correctly. Can you help?
