Screenshot: http://img14.imageshack.us/img14/835/whistenoiseflashmine.png Tried the same videos in Chrome and IE and they behave normally. I have DW Font rendering on, but couldn't verify if it is the reason for it. HW accleration in Flash is off. It started a few days ago only on videos, but I've seen it today on some other flash heavy site I've visited, too. Reproducible: Always
