Be sure your TV show folder and episode files are named correctly so the information about them can be properly scraped from thetvdb.com. See here for details: http://wiki.xbmc.org/index.php?title=Vid...s/TV_shows
Check your debug log(wiki) to see why these shows aren't being recognized (probably due to naming issues, as mentioned in first bullet)
(Moving thread to Metadata Scrapers since it is unlikely an iOS issue)
