So, recently I have run into a (new) problem with YouTube, simply that half of it doesn't work.
And by saying, doesn't work, simply means that it doesn't load. Yet the strange thing is, that some YouTube videos do work.
Currently what I can't get to working right on my mind is Nazgrim and Lorthemar from the recent news post.
I tried right clicking to get the stats (for nerds), and it did show me no bandwidth at all.

Any solutions for this? I tried restarting computer, browser and clearing all caches.

Computer:
MacBook mideo 2010
Mac OS X 10.7.5

And before saying that this is a mac problem, I tried with the exact same videos on my windows desktop, and had the exact same problem.
