Iphone 5 w/ios7 embeds not resizing

I am using the embed code from the Kaltura player site and it is not resizing properly on the iphone 5 operating with iOS 7.0 and 7.0.4. The playlists are not resizing on this page:

Once you click on it, it’s fine and plays normally. But the thumbnails are showing up too large for the playlists. Is this something I should be targeting with CSS?
