The long and short of it is: YouTube decommissioned the old API we were using. That is why you might have noticed some empty, videoless YouTube modules right now.
We’re aware, and we’re working to upgrade to the new API. Smarter brains than mine (ie, Gil!) says the module will be back in action by the end of the week.
Thanks for sending in your bug reports and for your patience as we fix the module.
