Happened to me as well. Can't understand why huge companies with a wide variety of visitors use techniques that deliver sub-par experiences so often. I'm running the latest version of Firefox with a $2k Macbook Pro.

I tried three different browsers. Opera was very laggy, Chrome just showed one frame and Firefox was moderately laggy. Resizing the tab helped a bit. Audio was choppy as well. My HW specs are far from low (though it is not a gaming machine either).

I couldn't pause the video, fast forward it or even see any indicator of progress. I didn't even expect volume settings.

Considering all this, the page is simply horrible. It might look nice (on paper perhaps), but the UX is the worst. Visuals alone don't make good sites.

seems ok here and my pc is not that great. (chrome/win8)
