I should probably have mentioned that I did as much due-diligence as I
could, and I can see that the MARK_KEYFRAME data is read out of
recordedmarkup during OpenFile, but I don't really understand why (since
the same data is also in the 'Q' frame), and from what i can see of the
code, using GetPostionMap isn't a backup for reading the 'Q' frame (My
original assumption was that the offset data in recordedmarkup was only
used if a valid 'Q' frame was not present (i.e. the file wasn't finished
recording), but this doesn't appear to be the case). Anyhow, that is
(mostly) why I'm confused.
