You're right: that doesn't look like mine. I just checked clicking the current Springsteen and Jones offerings at the Marketplace. I get horizontal bars only -top & bottom- with "We take care of our own", and "chasing Pirates". Generally, this is what I get. Otherwise, it's vertical bars on the sides -but, never both; I suppose the differences depend on how the videos were shot or converted. Also, the lower & bottom bars on mine are about half the size of the ones on your sample: my lower bar, for instance, is at the lower-right controls, not above them -before those controls disappear, that is. I don't get a truly full screen, but the wide formats are the same I get on other sites' "full-screen" videos: thin top & bottom bars only.
So, I'd guess it's a resolution or other setting on yours. Enjoy experimenting and good luck getting a better pano of that nice shot.
