Thanks, Harry, I hadn't tried it that way.

Actually I did try it with embed {width:100%;} and that has a similar effect. Still can't get dynamic resizing this way, but the content does resize when the page is reloaded at least.

Unfortunately the video loop playing in the MovieRoom Flash banners doesn't get resized by either method, only the black background changes size.

Still searching but don't see much hope on the horizon for any simple way to do this.
