I received the DVD today, and the short feature Give Me Liberty is indeed included on it. I was going to post a couple of screen caps but it has some kind of copy-protection, I assume, because my computer doesn't even recognize its existence. I guess it's a good thing I have a real DVD player and don't just use my computer to watch DVDs.
For details see previous post here. Reference also the original post at The War On Guns.
My recommendation: Buy it. Now.
