Youtube – How to determine if a YouTube video is age restricted

The views are broken down in Youtube's nifty statistics page per domain source, so you will be able to track where the video is being watched and where it is being shared. It is a pretty amazing tool for campaigns.

From checking the uploader of the video's channel on YouTube, it appears that the video in question has been removed by the uploader.

The relevant error message for this video is as follows:

ERROR: content too short (expected 15287800 bytes and served 1323)

...in other words the expected size of this video is 14.58MB, but only 1323 bytes was served from the server.
