Looking for video library scanner

As per subject title, I’m looking for a video library scanner.

The closest one that isn’t terribly bad that I’ve found is the Media Center or Media player platforms offered by microsoft. They ‘both’ play and help organise video files under a single frontend, which is exactly what I’m looking for.

However, what I don’t like about its features is the ‘monitor’ feature that wants you to use. I’ve too many videos and too much harddrive space for it to constantly monitor all my drives.

What I’m looking for is simply one that offers the monitor feature and just a possible one-time scan something along the lines of Picasa can do for photos.

I’ve got a variety of different videos to the point where I’d like to start organizing them through a frontend.
