Hmm... interesting. So that's the ArticleVideo extension ADEN's been working on.

It doesn't seem to be affecting the page load too much, but it pushes the content down so users need to scroll down through the ad to even know what is the page about. Could you make the video ad position on the page configurable through WikiFactory (or ThemeDesigner, as suggested by the above comment) as well? The API doesn't seem to be returning any value telling where should the video be placed so I assumed it's not configurable yet.
