Apologies if this has been addressed previously but I wasn't quite sure what to search for. I upgraded my iPhone 4S to iOS6 on Wednesday before I left for a brief vacation. I used my phone to shoot several videos while I was away. When I came back, I plugged my phone into my PC and copied them over. They open in QuickTime 7 Pro but I just get sound with a black screen. I figured this may be some kind of codec issue so I uninstalled/reinstalled QuickTime 7 Pro and rebooted my machine. Nothing. Then I noticed that all videos I filmed pre-iOS6 still play fine on my PC. It's only on videos I shot after the software upgrade. Is there something that I can do to play these on my PC, or some codec change that I need to be aware of? I am able to open the mov files in VLC and play them, but attempting to convert them with VLC gives me a corrupt, jumbled video. I'd like to be able to edit/rotate/crop some of the videos. Thanks for any suggestions.
