Ok, i thought i figured it out. There were two video tracks that were empty and turned off so i turned them on.. it seemed to help the lead in white track that was acting strange but not the flickers on the titles. And now there is a spot where it flickers the whole video.. so several layers at once go black for a frame...
When i scrub the timeline some of the titles flicker there too? But when i drag to a spot where the title disappears and let go of the mouse it reappears again.
