They have some videos online. In the upper right of the screen shot of the post above, notice that it has "Rocket City Rednecks " showing. You can find some videos for that show here:
Under "Nat Geo TV" they have a menu item labeled "Shows." Expand on that and you'll find "Rocket City Rednecks."
I just did a quick look at the video thumbnails for the Rocket City Rednecks show, not the shows themselves. Are they using Alibre Design as a basic tool for their various creations? That would be most excellent.
There may not be one, there are only six videos available and the longest one is only 04:48 long (that's four minutes 48 seconds). I watched all of them and did not see AD. It appears that the videos are only condensed versions of the full length TV episodes.
