Well, this is the first time it's happened to me. Anyway, It's in movie only mode and on the far left side, you see title, chapters, angles, and time. Usually, title 1 has the movie in it. But this time, it's title 11 (with 51 chapters).
Title 1 is selected by Default. Yet here, title 1 has 1 chapter 1 angle, and a time of 00:00:00 Did you select another title or just do it as usual and just select your subs etc?
