In Premiere CS5, when one placed an Encore chapter point on the timeline, it simply appeared and it was automatically titled with the chapter number. I liked how that worked. In Premiere CS5.5, when one places an Encore chapter point on the timeline, a dialogue box pops up which has to be clsoed, and if one does not add a title, then all of the Encore chapter points are titled "untitled." Is there a way to get CS5.5 to behave like CS5 in this regard? If not, I'll submit it as a feature request.
Use the button in the Timeline panel.
