I assume that the words in your suggested command line are all 
replaceable tokens because in the filters documentation 
(https://ffmpeg.org/ffmpeg-bitstream-filters.html)...
"filter1" not found.
".metadata" not found.
"mode" not found.
"print" not found.

The closest I can find is "2.20 mpeg2_metadata" and that appears to be a 
metadata writer. Am I simply looking in the wrong place?

It sure would be nice if ffmpeg documentation had a search function.

I'd tried google advanced search of 'https://ffmpeg.org' for a variety 
of metadata parameter names and got links to source code 
(ffmpeg.org/doxygen) but not links to documentation.

Could you give me a push?

UPDATE

Based on this:
'https://ffmpeg.org/ffmpeg-filters.html', section 16.11 metadata, ametadata
I tried this:
ffmpeg G:\VIDEO_TS\VTS_02_2.VOB metadata=mode=print
and failed.
