I posted my problems a couple days ago… seems like I’ve got some of the problems you’re experiencing, though only on text animations. Some of the blur and glow fx “pop” on the last frame, and I’ve not been able to remedy the mysterious floating text problem. I do notice a lot of jittering on the text when I’m using a blur fade in/out, but outputting a quicktime using motion blur seems to have solved that problem, at least reducing it to a more acceptable level.
