Changing HTTPS to HTTP for certain pages.

I need to find a solution to a problem i am having with certain pages on my website. At the moment i have an SSL certificate for my Drupal site, and a rewrite rule forcing every page to be HTTPS. The problem i have is for certain pages [login to view URL] [login to view URL] I get a security warning in Internet Explorer "Only Secure Content is Displayed .... Show all content" and people need to click "show all content" to beable to view the video in IE. What i need somebody to do for me is to provide me with the Apache code which will change the above 2 pages to plain HTTP: while keeping the rest of the site secure HTTPS.
