Popular question on positioning content exactly within iframe and I have only found one true solution however I can't perfect its use.
You should be able to quickly test it yourself and see that my example is a flash game which is boxed off nicely HOWEVER. If you put a div below the iframe it ends up about 500 pixels lower creating a large empty space. Its obvious what setting creates the exact height however when I change it from 794 to anything lower it effects the iframe content view. Counter balance has been impossible, maybe something I'm not getting!
Any help on would be great. I know iFrames are to be buried however I don't believe they should be and plan to use them a lot so help is great right now.

<iframe id='innerIframe' scrolling=no src=''>
_rect.push(-385);//moved site up
_rect.push(130);//increase window size to right
_rect.push(0);//extends or decreases bottom bottom
_rect.push(622);//changed overall view width
_rect.push(794);//Changed overall view height
