I know that Windows Live Photo Gallery 2011 stores people tags and other metadata like ratings in the photos themselves (see a very similar question about photos here).
I'd like to know if the program does the same for video files, which also can be given tags and ratings. I'd rather not annote videos if the metadata is solely stored on the machine on which I do the annotating.
I ask because I don't see the metadata entered in WLPG for videos in the properties window of the file in Windows 7 Explorer.
