It seems the code will only clear the recorded markup tables of records of
type "MARK_KEYFRAME"
if the flag "USE_CUTLIST" is not set. (transcode.cpp lines 268-303)
I'm not clear on the different types of records in the recordedmarkup table,
can someone explain to me please?
Shouldn't this table be cleared of *all* records for this file and the
commflag thread rerun if the transcode has actually
completed succesfully to a different format?

i.e. if the existing data for this file relates to the original (in my case
MJPEG) format, then isn't all the recordedmarkup data invalid for the
resulting mpeg4 file?

If anybody can confirm this I'll submit a patch.

thanks
Mark.
