First, excellent hack, well done.
The problem I am experiencing is that, in the vbulletin blog component, when someone posts a URL, (youtube for example), in the blog snippet it only shows the youtube URL, not the embeded video. you don't see the video until you click on that specific blog entry title. so most people click on the URL in the snippet and it takes them off of our site to the youtube site.
Is there a config in passivevid or somewhere in vbulletin that will change this? I have tried increasing the max lines in the snippet with no success.
