If you guys don't already know if you use the Youtube button when entering a Youtube video, or if you actually use the [youtube] tags around a Youtube link, it posts the video twice with a some weird text at the bottom.

It works fine if you just throw the link in the editor without tags. I'm guessing it's a vBulletin problem, but can't hurt to let you guys know. I've seen it on Windows 7 with Chrome and on Mac OS X running Firefox so don't think it's related to browsers either. I can take a screenshot if you want.

 

Thanks for bringing this to our attention.
