The best of its breed on the Windows platform.

I like it, but this version (0.7.36) makes Windows Explorer crash when I hover mouse cursor over mp3-files for tooltip (only with mp3). Well, I guess I'll stick to 0.7.35

The most informative of all freeware media analysis tools I'm aware of. Very easy and fast to use too, at least in Win XP, where the Windows Explorer right-click menu has a "Media Info" entry in case of nearly all media formats - which is intuitive and fast, the way most of us like to work, I guess.

In Vista, unfortunately, as so often, intuitive and quick has been abolished and direct right-click access works only sporadically, for a limited number of formats. To analyze other media types, short of starting the application manually, the only right-click alternatives left to users seem to be long-winded fiddling along the "Open with" or "Send to" routes (it's possible I missed a faster method, of course, but I was too lazy to invest enormous amounts of time and effort trying to make Vista work for me and gave up on it very quickly).

BTW, (the IMHO excellent) KMPlayer apparently uses a version of the same engine to display media information. After loading an audio or video file, it can be accessed via the right-click menu or by pressing "Alt & J". Then right-click menu option to click to get the info is, who would have guessed it, "Media Info".
