Media Inspector Mac 1.31 shows no rotation information to diagnose a display bug that shows up in VLC and Plex but does not show up in iMove, iPhoto, or Quicktime player. These Apple apps somehow are aware of the camera rotation information. This is not obvious (to me) in the report shown.
1) Apple's Image Capture app ( installed by Lion in Applications folder) also works in moving files to a Finder folder from Camera Roll.
2) Apple apps all rotate the resultant iPhone 4S appropriately for videos taken with Home button up, down, on right of on left. (thumb nail images do not have any defects)
3) VLC and Plex with Home Button on left (so the sound buttons are on top right) puts the image up side down on the Mac.
4) VLC and Plex With home button on right, the image is correctly oriented on the Macn
5)VLC and Plex With home button up, the left side of the image is on the top side of the Mac screen
6)VLC and Plex With home button down, the left side of the image is on the bottom of the Mac screen 0 
Using Media Inspector of a typical (ie viewed upside down) iPhone 4S video file, the results are posted below:

Maybe they changed the way to implement rotation info... I need a sample file.
