trailers .nfo files

[dyhometheaterguy 8]

I just downloaded the lastest update to Cinemavision and I noticed this in the update notes: Trailers: Content scraper will now read genre and rating from .nfo files

How does this work and how do I add them to the trailers folder? I assume I can put a genre for the trailer I download in the folder and it was analyze it from the actual movie genre to determine which trailers to play

I'm pretty sure that's referring to the .nfo file of your feature.  Meaning if you are playing a horror film, you can have it stream horror trailers or if you have a PG film, it will stream PG rated trailers.  The .nfo file should be in the directory with your feature film along with it's artwork, etc.
