LG Streaming Blu-ray Disc DVD player: Using USB to connect external disc drive with .mkv and .jpg files. The LG device separates the pics from the movies. I can either see a list of movies or a list of pics. I would like to see a pic, click on it, and the movie associated with it play. Please advise me of any coding I need to do on my external hard drive for my LG blu-ray player to do this.
