Cannot open .mov file using cv2.VideoCapture in Python on Windows

edit

I'm unable to open a .mov file using the stock Python OpenCV bindings from the main Windows distribution. The file opens fine in ffmpeg:

I downloaded OpenCV from https://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.0/ and copied the build/python/2.7/cv2.pyd file to my python/lib/site-packages directory. The OpenCV samples work fine with .avi files, but I can't open my .mov file:

>>> c=cv2.VideoCapture('file0005.mov')
>>> c.isOpened()
False

I'm not sure what I need to do to get this to work - any advice would be much appreciated!

Thanks, Matthew
