Since the MythVideo does not retrieve meta data or cover for the video files, I had to do it myself. This requires a script which will go over the files, and look them up in the Internet (IMDB, THETVDB.COM, TV.COM, etc), and fill the MythVideo database with the data. I look for a long time for something that will do it, but found nothing. So I wrote a script myself... The script will go over all the files in your MythVideo folders, and for any file without meta-data it will parse the video files names, and determine whether it is a TV show or a movie (not a TV show...), retrieve the meta-data from www.thetvdb.com or from www.imdb.com, locate subtitles from www.tvsubtitles.net, and last, it will get a cover for the file, either from an internet DB or a snapshot from within the video.
