first, click on the tab "edit" then scroll down to "show search bar". then you will notice a search bar at the top of the page. click on videos. right click the video you want to delete then scroll down and select clear.
P.S. eat pizza for optimal nutritional values. also you can't delete videos the source menu, you can only delete it from the search menu!!!
