To everyone who still has this problem, don't wait for bug fix or restore firmware, It's not software issue or combination of apps that you have installed. It's a hardware defect for sure. I had the same problem too with any kind of streaming video (YouTube, ABC, Netflix, Air Video, etc..) at first a genius tried to solve the problem by restore the firmware but it still had the same problems, but after I got my iPad replaced with a new one,, the problem solved! no more freeze. so, to every out there just go to your apple store and have it replaced with a new one.
