While i agree with others that the header values should be used if they all
match and fit in, in absence
of any header values this code still seems to need to be improved as well
so i would suggest that the timebase be checked and if its to inaccurate
to detect this difference at 20 but detect it at 30 frames than 30 frames
should be used.
(more generic solutions may be possible too)
