Variable width using the Youtube Onebox, which is currently fixed

Continuing the discussion from How to embed youtube (and other) videos?:

Would be great to be able to set it per video or automatically-wide as the post. I could not find another Plugin that lets me do this. Example post w/ video where Iā€™m facing ugliness :frowning:


I know this is an old request, but I, too would like to see this. It would really make the posts with videos look nicer, cleaner.
