title: cannot import cv on OpenCV2.1
body: <p>I have downloaded OpenCV2.1 and Python2.6.</p>
  
  <p>when i try to <code>import cv</code> using <code>sys.path.append("C:\OpenCV2.1\Python2.6\Lib\site-packages")</code> and  then <code>import cv</code>, it tells me <code>ImportError: DLLload failed.</code>.</p>
  
  <p>I have tried the solutions given in previous thread to copy the two files in the above path to <code>C:\Python26\Lib\site-packages</code>, but i still can't <code>import cv</code>. </p>
  
  <p>Is it because I missed out doing some steps after installing? What could be the reasons to why the system cannot find the module <code>cv</code>? </p>
