The plugin no longer works. The author of the plugin is going to be out of town and not going to be able to fix it until next week some time.
Apparently YouTube made some changes to the HTML on there page so the plugin isn't able to parse for the links now.
Just hang in everyone, zbop (the developer) will fix it for us.
Any problems you guys have should really be directed to this
forum here, for this is the official forum for this plugin where developer communicates.
