134.  This is the only stat that I know for absolute certain as I have every DVD catagorized in a spreadsheet by genre.  Geek?  Me??  *astonished look*  Biggest group is comedy, leading the pack at a whopping 30% of the collection.  Coming in close behind that is Sci-fi/Fantasy at 21%.  And when I say genres, they are sorted by what I consider them to be, not IMDB or any critic.  The collection exploded into being two years ago and has steadily dropped in additions.  I'd say it's about one every other month now.  The trend will soon be broken however when Mr. And Mrs. Smith, Charlie And The Chocolate Factory, Serenity, Batman Begins and Mindhunters all go previously viewed.
