Yes I tested it on both Chrome, IE and Firefox (my main)
In the other topic with buffering issue you can see what exactly happens, my internet doesnt stop, if I'm playing a game I dont just all of a sudden lose Internet, but when watching a video all of a sudden it doesnt want to buffer any further.
EDIT: I'm sorry, apparently it doesnt bug out on Chrome or IE, just Firefox. That's odd, a few days ago it was everything.

Now with Chrome! :
(It did stop buffering after 8minutes for whatever reason but it was more lag (my connection) as it showed spinning circles then started again, on firefox there are no spinning circles, it just stops and never goes further.)
But it did buffer it all?
I also have this issue with
Twitch.tv streams. It's not JUST youtube, and it works in Chrome I just learned..
