Any wordpress theme can be made into a tube theme. You must not understand wordpress, and how to turn any blog into a video blog.
Examples:
http://bobbistar.bdsmvixens.com
http://freecreampievideos.weirdporntv.com/
http://kinktube.weirdpornsearch.com/
All of those are multisite and mines. I dont know about free wp tube, i think these guys make tube themes too cookie cutter and too complicated. Why does everyone want exactly the same site? Surfers dont care about a tube design all they care about is the videos. All of my wordpress video sites work with me copy and paste or an auto update xml feed.
