I tried clearing cookies, IE history, nothing helped. I right-clicked the video, disabled the hardware acceleration but still no avail. Firefox shows same behavior. I installed Flash Player earlier but found Firefox demanding a fresh install. Yet nothing improved. At my Win 2003 server though, there is no such problem. Everything works fine even in IE 8. Any guidance is welcome. (I never had such problem in all 20 years of my PC usage, just wondering what went wrong?). I have all updates installed.
