Hey everyone,

I’m embedding a youtube vid on a site for a client.  
The parent element it’s in has a percentage width, so it’s of course always changing.

What I need is to have the vid’s proportions stay the same (I think the width to height ratio is like, 4.25:3.75).

In Firefox, setting the object’s width to 100% and leaving the other blank works fine, but not in IE.

I’m using the SWFObject - but I need to find a way to have the video show in it’s normal ratio irregardless of its parent element height and width.

I also tried using the width: expression(… for IE, but it didn’t pan out.
