Hi,
that's a 'custom' error page from the youtube webmasters... the content looks like the stream bytes for the 'video'.....(the standard 500 error page does not have a blurb about monkeys.... Bozo was once the throbber for Mozilla browsers.
the first test for troubleshooting issues in IE (and other browsers) is to use noAddons mode (the video is html5 video, not flash, so it'll work in noAddons mode.)
I could not reproduce the issue from you provided link, but I see in your 'Video' that you are using the Yahoo toolbar in IE10.... I imagine also that the YTB will be installed also in Safari (whether or not you wanted it).
My money's on one of your addons... what security software do you have installed? I think yahoo call their 'free' version 'spy'... something...
on yt video elements you can select the debug info from the <video> elements' context menu.

since the error message is a customized message from the yt servers, I would suggest that you use the yt feedback links, but my money's on your addons.
