embed formatting

It seems with youtube’s new player implementation is buckling the formatting on my page – the embedding no longer accounts for the height of the player bar and so reduces the size of the video leaving nasty black vertical bars on all my embedded clips – is there a way add the extra 35px player height and maintain the correct porportions of the clip (while still maintaining my 600px maxwidth)

In this example the clip should be 600px x 338px +35px height for the container

I would be very grateful for any assistance
