As the title says, everything works great except the video thumbnails not displaying when viewing the special page: New Videos. The html code created doesn't have a link to any thumbnail image or small version of the video.
div class="thumb" style="padding: 23px 0; width: 230px;">U2</a>
I'm just testing with the trunk 1.22 wmf12 mediawiki, because I also need the visual editor to work. Not sure if it works in earlier releases.
