I'm actually having the exact same problem as above - the video - when I use the embed code in the post editor itself (in this case from TED conference) shows up re-sized and way too small.
Alternatively, when I use the embed within the big feature settings options beneath the post, the video shows up per the desired size (per the paramaters set in the embed code) YET....it gives a very big empty space between the top of the post title - and the video itself. (i.e. - readers will have to scroll down uncomfortably to even see there is a post associated with the video)
Here is an example -

(this blog is only now going live - and this post is "hidden" to the public - but I have a broadcast to a newsletter list planned for this post - so I would like to see it work properly)
As a quick aside - on single pages with NO sidebar- I'm also NOT having the page title show up on the page itself, I've been manually editing titles into the post body itself using h1 tags...not sure why these things are occuring - love the theme otherwise - and really want to use on this project!
Thanks so much -
