I'm just starting out with Plex. I have been making mp4 movies for ATV for a while. I have a large collection (275) of 480p movies, about 75 movies at 720p, and now I'll start keeping 1080p mkv's of my favorite movies for the Plex/Mini box. My question is, how do you keep them organized so that you don't have the same movie showing up 3 times in the Plex library? I've figured out the CNID for the iTunes SD-HD flag and I've been consistent with that on my 720p files if that helps, but I am guessing it won't. Another Plex library question I have is if I just add my iTunes folder to my Plex library and flag it as music, my music videos and the movies folder in iTunes (purchased movies that apparently won't play through Plex anyway) won't get flagged properly. I'm going to continue combing through the Plex guide, but prefer to get input from people who are using it so I can set up the best file structure, etc. Thanks.
