I have a "Movie" Content type lister set up to show Data Rate, Bit Rate, Duration, etc. All fields that are specific to movie/video files are blank. File Name, Size, Modification Date display ok. This may have occured after the most current software update.
If no configuration changes were made (e.g. disabling the Movie plugin) then something has broken the video codecs/splitters on your system. See HOW TO: Enable/fix playback of various media formats in Opus for suggestions.
(In the future, we'll be making this metadata less dependent on external codecs.)
