firefox4+html5

Hi, list!
    I do not know in what part of forum to write, so I decide write in General.
    I'm trying to use html5 on youtube.com. I getting the video stream, but audio "stutters" on most of video files . I tried to use the chrome-browser and he is works fine. Also, I tried boot from usb flash drive with installed ubuntu and firefox 4 and this works. 
So, I believe what trouble is in my FreeBSD.
