Can not view YouTube videos in full screen?

First run updates of Flash Player and your graphics card and restart the browser.
If you still can not see the video full screen click on it with the right mouse button and go to Settings - View where you remove the tick in the \"Hardware acceleration\".

For two days I can not open multiple movies with YoutTube. I get the
written \"Maybe you have disabled JavaScript or you have an old version of
Macromedia Flash Player. Get your version of Flash Player latest. \"
Obviously I have reinstalled Flash Player, but without result. I also
tried to restore the configuration of IE7 but not here
result.
How do I check that JavaScript is enabled?
Who helps me?
Thank you.

Solution:
It \'a problem of the location of Italy.
Top right click and select Global Site.
Magically, the video will start to operate.
