Please visit the site and click on the logo. The site tries to precache a video stream, but never ends with this operation, so no video is played. If you select other video streams from the menu bar below, only randomly a video is precached and played. If you open this page with nightly build Firefox 3/Minefield with the same version of flash plugin, the page always streams the videos correctly.
Confirmed. But it's an evangelism bug. The issue is absent with User Agent set to Firefox. I think the script is responsible for the issue: http://www.neave.tv/history.js The project responsible for the script: http://www.unfocus.com/projects/historykeeper/
As I tested today the video stream plays fine in WebKit r35203. Closing as fixed.
