Greg @ WP YouTube 2
I am running WP v2.9.1 and WP YouTube v2.0. I was also using the plug-in WEBO Site SpeedUp. My site and the wp-admin of WEBO slowed WAAAY down after installing WP YouTube. Also, Google Chrome started complaining about a mismatched tag. Sometimes, you used , other times you used . I converted all the usage to and my performance came back and Google Chrome stopped complaining.
