Well, besides the stupid age gate thing (not GT's fault, it's a moronic industry standard that does nothing but be an annoyance), I did have an issue trying to hit the little full screen icon in the bottom right. It just paused the movie. In fact, clicking on any of the icons down there did that, so I couldn't change to HD mode, change the sound volume, or watch it in full screen.
Tested on the Dark Souls video here: http://gamingtrend.com/2011/08/17/sadistic-gamers-and-their-dark-souls/
in Chrome. The 007 video seemed to have full functionality.
I was going to test more, but I kept getting ads so I gave up. Which leads me to: I can't say I'm a fan of ads, but I guess that's how things go.
