I found a method for your support people to determine what is going wrong with my unit, it's not longer just stopping on live youtube items but on certain live videos that have now been saved as normal by youtube.
This video, on my brand new ultra plays till he says 5 second mark where he says "today we're going to discuss cost of living", it was stopping EVERY time at that point. I then went and watched it on the Youtube player in my Samsung and it played fine, never stopping. Now when I go back to the Ultra and rewind (cus it knows I've watched it on another player) and watch, it does NOT stop, it goes past that part perfectly... this is messed up big time..
