No reason to be hostile. We investigated months back when we got reports from our users, who are professional videographers, that videos were showing up much worse in some browser situations than others. They sent us screen shots, and upon investigating found that on almost every clip we were getting better results using two different flash players we had access to than the native decoder.
I don't have some big official report because, well, that's not my job and I have better things to do. You're welcome to investigate yourself if you're concerned about it.
