How about it? I've seen this over at www.flashkit.com and it looks really good. All you have to do is add to your signature something like [swf width="300" height="40" background="#FFDDBB"]http://www.site.com/mymovie.swf[/swf]

You can also change the dimentions by changing the width & height values, but it's not recommended (it will take too long for a page to load)
