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.
Same issue here.
The video also does not display when the article containing the video is transcluded to another article. For example, on page foo, I have [[Video:foo|300px]] and that page displays properly. On page bar, I have {{:foo}} and the only thing that displays is a hyperlink with the link text '300px'. The hyperlink goes to Video:foo which also displays properly.
