Why should the user have to enter any code at all? Am I misunderstanding this?

Since you are limiting this to "the big video sharing sites", why don't you have the user simply plug-in the URL to the video, and then YOU add the necessary embedding code to the page?

You will of course have to carefully check the URL for validity.
