|I think I figured it out.|
When you rotate a picture on the PC, it marks the metadata as to the rotation angle. If the picture was never rotated, it has no rotation data.
When the TV shows the picture it shows the angle of the LAST picture that had rotation metadata. All the following pictures will end up with that rotation until another rotated picture is shown.
The workaround is once you get all the pictures in the PC at the angle you want them, select all the photos in the folder and rotate them, then rotate them back. This will mark every picture with rotation metadata.
