The video appears to load but then I just get a spinner and nothing happens. I have tried youtube.com, operavision.eu and metopera.org. All fail. I have installed ubuntu-restricted-extras, turned off acceleration in firefox's preferences, and generally tried all the suggestions I can find on the web. Lots of people seem to have this problem.
