I have quickly tested that site and I too had Jaksta crash shortly after the video started playing. I think it is safe to say that this is due to a change made to the site that Jaksta reacts badly to, and it will require a fix.
I will add it to our development list, but we have some other high priority issues we are currently working on so no ETA as to when it will be ready. If it's easy enough then we might be able to get the fix bundled into the next update, which should be in the next week or two.
