An interesting little program I came across which allows you to view just about any information on your media files is MediaInfo. From their description:

MediaInfo supplies technical and tag information about a video or audio file.

Simply put, that is what it does. You can extract just about any information you can think of from vitually any audio or video file format. Additionally, you can export this information to a text file format and the available command line interface gives you the ability to create a batch file to quickly gather information on your entire media library.

While I personally cannot think of any true practical applications for this program, if you can please drop a comment.
