Sadly Twonky does not support metadata from nfo files
But it does read embedded metadata for most file types
You can use a couple of programs to manage the metadata
TwonkyManager will do it, but it enters the info into the db directly
and does not add it to the file,
but can be useful for file types that dont support metadata
however if you ever rebuild your db, you might lose all the info
All of my videos are in mp4 format and I use
mp3tag
to add cover art, genre, year, etc.
Also, recently
MediaMonkey has added support for video tagging

I know they are about navtree editing
but in doing that one would need to know what is possible
I pulled out what is kind of possible for metadata usage below
dc:date The date of the item YYYY-MM-DD
dc:description The description of the item
dc:title Main title of the item
upnp:albumArtist Album Artist
upnp:artist Name of an artist - always use with role=Performer here
upnp:author Name of an author - always use role=Composer here
upnp:genre Name of the genre to which an object belongs
I know its a lot to absorb
and kinda of all over the place
but it is what it is
PS
genre at the moment
is the only multi vairable supported one
and it only does it when they are seperated by a "," not ";"
for ex:
Action,SciFi,Funny
