footer issues

For some reason on my new site redesign, the footer is not working properly on smaller resolutions. Its all set at 100% width, but for some reason its not working right.

Can anyone tell me what i’ve done wrong?

Also I have a box that isn’t displaying on my posts its a div called video but its not displaying on the page, any ideas about that either?
