After running an automatic update for the flash player, the YouTube videos stopped working in the forums! The youtube BB code uses an activex control to run the imbedded youtube video in the browsers flash plugin. I had to turn around and install the flash version 10 activex stand alone installer to get the videos working again. Here'a a copy of the installer:
