VidFile?

[DanaPaul]

What would be the most subtle way to determine if a file also contains Animation, Video, Mov. etc... independent of (screwball) file name extensions?

Would searching for a short list of FOURCC Id's in the file (stream) be reliable? Or would I have to go the Codec (file) association route?

MCI commands and the examples posted at the Microsoft site just aren't standing up to the task  :-/
