When I view http://wordpress.tv/2011/08/20/nikolay-bachiyski-unit-testing-will-change-your-life/ it doesn’t list the event, similarly for all but Matt’s talk, though they are listed at http://wordpress.tv/event/wordcamp-san-francisco-2011/

Search result template doesn’t allow clicking on text of results. You have to click on the thumbnail
ex. http://wordpress.tv/?s=state+of+the+word
Browser:
Mac Firefox 6.0
Mac Chrome Canary 15.0.859.0

Aside, the thumbnails are so small that they are not interesting or useful.
