In previous versions of WordPress, I had set the maximum width of auto-embedded videos to be 590px. It worked perfectly.
Now that the ability to set the maximum width has been removed, my videos have reverted to a smaller width. I don't believe that the new version of WordPress is auto-detecting the max width as advertised.
Other than specifying the video width using short code EVERY TIME from now on (not to mention the 100 posts that I'd have to go back and look at), is there anything that can be done to set the maximum width of all videos?
Example of video that was once 590px based on media settings, but isn't anymore with 3.5 update: http://www.owlandbear.com/2012/11/09/video-the-sea-and-cake-harps/
