Correct video properties are hard to assess - this is why OpenCV is struggling to offer a solid VideoCapture (CvCapture) object, but until now, it still have some inconsistencies.
What you can do is to install more codecs on your machine, or convert the avi file with a codec that works better on your installation (this is a trial and error process).
Many others have similar problems, and here are some tips from them:
