problem with cvCreateFileCapture of openCV

Hello everyone,

I want to use OpenCV on a software I'm creating in my lab.

This week I changed my computer and and installed from scratch all the softwares I needed, including OpenCV and python2.5.

On my previous computer all worked fine, but on the new one I have a problem...

Whenever I use the cvCreateFileCapture function it returns None (I'm coding in python).

I can run most of the samples (those which don't require a video stream), for instance the facedetection on an image works well.

Both my previous and my current computer run a vista japanese business 32bits edition. I have all the codecs to read the video I want to process using OpenCV.

Does anyone has experienced the same problem and found a solution? Any help will be greatly appreciated!

OK a fresh update:

I converted a movie using

mencoder cat1.mpg -nosound -ovc raw -vf format=i420 -o out.avi

and this works, I can launch the cam-histo.py sample with the out.avi file... So is it a codec problem??? I really don't understand...
