Why can't I open avi video in openCV?

Question

I just wrote a simple video reading example with openCV2.3.1, but it seems that I cannot open avi video anyway :(

A missing OpenCV's ffmpeg.dll does not generate any warnings/errors in OpenCV 2.3.1, and code fails silently. Make sure that you have proper opencv_ffmpeg*.dll in your path.
