Sapphire and information

I have in the movie folder on my Apple TV a movie map with 2 avi files. The map have the name of the movie and the 2 avi files also.
Sapphire find these files and get the information from IMDB.
But I have also 10 movie maps with a video ts files in the folder Movies. But sapphire don’t find these movies, so i cannot get the information from IMDB.
I can play all movies with Nitotv.

Someone an idea?
