Just to be clear, by "mediainfo-type metadata" I mean technical info about video and audio codecs, number of channels, etc. NOT TMDB-type metadata about actors, genres, etc. I've updated audio tracks for a large number of videos in my collection, but my Z10 Pro doesn't show different badges for the updated audio on the Poster Wall until I manually refresh each show, one at a time using the "More..." button and then the button. The "Refresh Metadata" pop-up menu item doesn't seem to work to update mediainfo on all episodes of a TV season as I hoped it might, which wouldn't be all I want, but would have been an improvement over refreshing one episode at a time. I don't want to use to "Update" option to re-scan my entire video library, since I'm afraid that will wipe out all of the matching corrections I've done manually to fix mismatches made by automatic scanning.
