OpenCV cvReleaseImage Crashing Problem

...
frame = cvQueryFrame(capture);

cvReleaseCapture&capture);

    I found your stuff through Jon Carrier's site. I wish blogging had been more established when in graduate school- I like to share what I can, and I think better when I am trying to explain something to someone else.
