OS: WinXP Home 2002 SP3
Browser: IE 8, Chrome 10, Firefox 5
Symptoms: Click on a video, browser goes to that youtube page, get the little white dots going around in a circle on black background. White dots freeze, video starts playing, sound works OK, video stays black with the circle of white dots.
I un-installed Flash Player and re-installed 10.2 (IIRC). That seemed to help IE for a moment, but now the symptoms have returned.
We’re running AVG Anti-virus and it is up-to-date, so I don’t think it’s a virus.
Tried YouTube help but (aside from the Flash Player re-install) didn’t find anything helpful.
