Comment (by emcodem):

 Conversion works when disabling filter reinit:

 ffmpeg -reinit_filter:v 0 -i Interview.mxf -f null -

 The mpeg2 stream changes from transfer 2 (709) to 0 (unknown/forbidden).
 Might not be trivial to catch this special case of changing to unknown
 transfer characteristics in which case it would be best to just keep on
 working with the current transfer char.
