Exiftool and video metadata

I am trying to use AdvancedRenamer to create names from video files (in mkv containers) and it looks really promising.

But Exiftool within AdvancedRenamer is not seeing all the available tags - outside of your tool I can use the -a switch to see them all. Can your tool allow the -a switch? Can it handle having tags with duplicate names, eg.

Tag Name : DATE_BROADCASTED
Tag String : 2015-07-15 14:00:00
...
Tag Name : PART_NUMBER
Tag String : 7
...
Tag Name : SUMMARY
Tag String : The Apology Insufficiency: ....


thanks
Neil
