Thanks. The durations now look like what shows up during playback.
Interestingly, at least in this recording, the end times of the cc708
captions are usually within a couple frames of the cc608 end times,
but the cc708 start times are usually substantially later than the
cc608 start times, making cc708 a lot harder to use. Mythccextractor
is a great tool for looking into this.
