I got it to validate (Dreamweaver)like this:
<object type="application/x-shockwave-flash" data="movie.swf"
width="750" height="140">
<param name="movie" value="header.swf" >
</object>
It's funny that many ways Dreamweaver does things won't validate to their on validation criteria!
Both movies are so small that IE's streaming problem will not effect the outcome in this case.
I'll try it W3C in the next couple days.
Thanks,
