Take a look at cvCaptureFromFile, cvQueryFrame and cvSaveImage ! They'll do everything you need.

Thank you very much! Do you happen to know how I convert the received image into gray-scale? Thanks!!! – N.M Jun 07 '11 at 08:52

If you're more comfortable with using the C++ API, the VideoCapture class (see http://opencv.jp/opencv-2.2_org/cpp/highgui_reading_and_writing_images_and_video.html#videocapture) is very convenient to use.
