Loading external swf file in a movie

I can’t find any tutorials on the web on this so I thought maybe someone on here might know how or maybe I just missed the one on this site.

I want to make a webpage in flash and have buttons on it that would showcase my animated cartoons I’ve done. For example, say the webpage is a giant TV with buttons on it. You click a button and then a cartoon from an external source (i.e. my webspace) loads on the TV screen.

Does anybody know how to do this or is this even possible?

Thanks.
