/**
 * Revision3 Video SEO Details
 *
 * {@internal [JRF] We can get much better information (duration, thumbnail, content_loc from the
 *            author RSS feeds, but then we'd need to know the author in advance and the individual
 *            item RSS address which I currently haven't been able to figure out.
 *            Even if we just had the author and episode nr, we'd be better off as we could construct
 *            the thumbnail and content_loc, unfortunately, we normally won't have those.
 *
 *            For future reference:
 *            Content_loc: http://videos.revision3.com/revision3/web/[author handle]/[Episodenr - 4 digits]/[author handle]--[Episodenr]--[Episode title]--large.h264.mp4
 *            Thumbnail_loc: http://videos.revision3.com/revision3/images/shows/[author handle]/[Episodenr - 4 digits]/[author handle]--[Episodenr]--[Episode title]--large.thumb.jpg }
