Playlist

Someone please tell me how to prevent my playlist from randomly skipping.
I've tried playing my videos in sequence by clicking sort then by title, by
rating and by file name. That does not work. I've also made sure that skip
isn't checked. In addition, under create auto-playlist I've created a
playlist and selected sort by title in decending order and added each title
name of my video then clicked OK. It still randomly skips. I have some multi
part series that tell a story that need to be played in sequence. This is
very frustrating. Will someone please help me?
