YouTube has a “feature” to protect you from content that may be considered “inappropriate for some users” – forcing you to log in to pass an age check before you can view a video. We’ll go through a quick URL change to get past it while not logged in.
We’ll be using the above Assassin’s Creed 2 trailer as an example of flagged content. Take a look at the location/address bar, and you’ll have something that looks like this:http://www.youtube.com/verify_age?next_url=http%3A%2F%2Fwww.youtube.com%2Fuser%2FAssassinsCreed%23p%2Fu%2F17%2FUBzWURM02Ks
You’ll want to change it to this, by removing everything after “youtube.com/” up to and including the bold “%2f” and replacing it with a “v/”http://www.youtube.com/v/UBzWURM02Ks
Hit enter, and you’ll view the video. The drawback is that you’ll see it the size of your browser window, and you won’t be able to see anything else related to the video:
It’s a quick hack that doesn’t require anything other than a URL change and takes advantage of the fact that YouTube doesn’t do an age check for embedded videos.
