Hi
I'm seeing the same thing on some of my videos?
If I go to Windows Explorer and right click on a video file, and select Properties, then go to the details page I can add or remove content as you can see in the image below on some of my video files, (these were all created by me).
Here I have added the Titles and set the Rating to 4 Stars.
Link Removed
I think that I had to click on the Remove Properties and Personal Information before I could do it.
But on other video files in the same folder, I could not edit the information, and I can't see any difference in the files or the permissions.
I tried setting permissions for the other files to everyone but it still won't let me change the information.
It just doesn't give...
