Are you in Germany? Because that's the country that is usually blocked. It's not blocked in America, though.
Also, I updated the video, because the quality sucked.
It's only blocked in some countries. Sorry if it's blocked in yours. I can upload it somewhere that doesn't check copyright as well (I can't wait until YouTube gets replaced by something a little less anal about silly fanvideos that aren't making a cent)...
I'm in California, same as you, and it's blocked, both the vid in your first post and in the one I'm quoting here -- same message, both times.
And YouTube doesn't check copyright -- they simply respond to complaints about specific clips, which complaints are registered by the copyright-holders or by their representatives. Warner tends to be particularly aggressive about protecting their copyright, as are Paramount and NBC.
