OK, i just had a try on this but honestly i don't know how this could 
work without a very deep change of the whole mxfdec.c.
The problem is that i cannot just add a field to the struct 
MXFMetadataSet as this points to raw data which has been read from the 
mxf file. I could add a field but if i initialize the value, i will 
automatically destroy the original raw data which was read from the mxf 
file.

In case i did not miss anything, i guess the 1-line change i sent is 
kind of best effort: it should not destroy any existing funtionality but 
in certain cases, it delivers more accurate metadata.

Lemme know your thoughts!
