Hello to everyone!
Firstly, I would like to say that I'm using the latest version of Google Chrome (9.0.597.197).
As far as I know, the flash player is integrated in the browser so it should be up-to-date, too.

I have never been able to watch fullscreen videos on Chrome. It just gives me white screen.
When Youtube changed the design a few days ago, the videos even stopped showing at all (only the first video I try shows up, the following do not). There is only sound.



I'm only able to view them normally through someone's channel, or if they are embedded.

I've tried uninstalling and installing again Chrome and Adobe Flash Player but with no result.
I also tried this method but it didn't work either.

Same goes for Firefox and IE. I'm using Windows XP SP3, if it matters.
Any help will be appreciated, thanks!
