Youtube freezes on Internet Explorer 11 (Windows 7), works when Flash is disabled

Hi,

I have recently upgraded to Internet Explorer 11 and since the upgrade, every time I visit a page on Youtube, the page will freeze for a good amount of time. I have been able to reproduce this on all of the computers in my house. However, this problem disappears when I disable the Adobe Flash add-on in IE11. I did try the new Flash Player 12 beta, but I am still having problems with the website unless Flash is disabled?

Please help.

I didn't find the right solution from the Internet.
