OK -- I figured out how to fix the problem with IE giving errors on page with vBadvanced using the Lite version of Passivee Video:
Go to manage plug ins -- edit parse_templates
Copy the code in plugin to Word Pad
Replace all
with
Code:
src='{$vbulletin->options['bburl']}/clientscript
I hope this save people the time I could have saved with clear instructions somewhere.
