That option grabs all videos at the same time. The best new option is the queue function that is automatically enabled. It will add the videos to queue and add them one by one :-)
Hmm...the graber queue in Admin -> tools -> cron scripts must be active. If you now activate the queue grabing in Admin -> Video -> Grab Multi it will go to a blank page? If you enable debug and then retry what error do you get?
when the debug is on it says this.
