So I have been shooting lots of videos using my iPhone 4s. I am filming the videos in landscape mode, and I want to back them up to my PC. I back them up to my PC using the recommended method (http://support.apple.com/kb/HT4083), but when I try to add them back to the phone through iTunes as "Videos", the orentiation is messed up. The videos only play as if they were filmed in portrait mode but in the landscape format. In other words they are only using like 30% of the width of the device. It's very bizzarre.
Does anybody know what I'm doing wrong or how I can fix this?
