Gallery Width

Hello. Rio is an awesome plugin, but I am having one issue at this point. I have a page for the gallery (shortcode pasted there) and can get only 2 videos per row to show up. I’d like the video thumbs to span from the left of my theme’s template to the far right sidebar. The page is divided into: 2/3 (left side for Rio Video Gallery) and (1/3 right sidebar). How can I accomplish this?

Here is the link to the gallery: http://tribyoot.org/video-gallery-2/?preview=true&preview_id=11004&preview_nonce=fbd8d62983

I appreciate any help you can provide so that I can get the most out of Rio.
