each one of my movies are ripped into a folder and the folder is the name of the movie. Inside the folder contains VIDEO_TS files and so on.
When I open MP and hit F3 to search IMDB it always searches for "Video_TS" so i then have to do a manual search and type in the movie that i want to grab info for.

Your setup sounds identical to mine except that when I select and movie and press F3 it searches IMDB for the title of the movie based on the name of the movie folder NOT VIDEO_TS.
