[Mark Susman] “Additionally CS4 crashes when playing the timeline and clicking chapter advance buttons.”
I don’t see that at all, although it may have something to do with your subtitles. I don’t have any 2.0 projects with subtitles at the moment, so this may be a subtitle-specific problem.
Try this: open your Encore 2.0 project in Encore CS4, then do a SaveAs on the project and save it with a new name. Does it still crash? Make sure you are working with the CS4 file now. f you delete the subtitle tracks in this project, save in Encore, and then add a subtitle track?
