This area and the area on the right is set at 160px wide ... tower ads appear to be 160px wide.

- The center area is 630px. The area for each video is 200px with the picture set at 125x90px..... could ba a bit wider... we just need to come up with a standard.

Also take a look at the youtube pages... there is a bit of info across the full width, below the tabs and above the 3 columns. What info would you like there?
