Hi Shadow, and welcome to the Hunt. (I don't suppose you live in Virginia, do you?)
As for what the video "Assurance" is about, you need to understand the story as it was a year ago. (Has it really been that long??!!)
First, the Poochee and Pansy videos go up (warning: screamer!) and we start to watch them, try to figure out what they mean, etc.
The last one led us to the Gangadiddle. We came to find out that the Poochee and Pansy videos were created by this guy "dolst" and his company "dolst family entertainment", but that the company had been stolen from him somehow, and he was going to get it back.
Next thing we know, he's standing before a camera telling us how he's working for the company now, looking terrified and reading from a script.
About that time, we learned of the "Isolated Worlds" in which we were all trapped due to the Gangadiddle (which is likely pronounced "Gahng-GAH-did-AH" or somesuch, but nobody says it that way but the s33k3rs). We found that everyone around us were puppets, and the dolst that got captured was just a puppet.
Meanwhile, in the real world, the real dolst is going about his business, completely oblivious to all this, until he is contacted by Hoodie, who bound the Gangadiddle. Hoodie gets dolst to make this video, which Hoodie then sends to us as a "Reassurance" that the real dolst is alive and well.
Later, the real dolst would be given the memories of the puppet dolst so he could help Hoodie with the Hunt.
dolst also got possessed by the Gangadiddle when the binding was weakened due to the Hunt starting early. Then, in dolst's body, the Gangadiddle bound Hoodie, aka the Hunt Master. We were given clues to reveal Hoodie's name, which turned out to be Nathan Israel.
Then, in Ganga-dolst's last video, just when he was about to perform an incantation to take over/destroy the world, Nathan Israel stepped into the frame and Vulcan neck-pinched Ganga-dolst and we all lived happily ever after......
......until the s33k3rs came along. hehe
Confused yet? It's a pretty convoluted story, that's for sure!
But the main core of it involves actually physically traveling to Virginia to find clue after clue to lead us to the "shrunken form" of the Gangadiddle.
Naturally, right about the time this whole thing started, I moved out of VA. :-(
So, as far as that video, it's just the real dolst telling us he's okay, but it's kind of old news now.
For the latest of what's going on, you can check this thread:

Hope the complex, already-in-progress storyline doesn't put you off. We can always use another brain and pair of eyes to help with the puzzles (and we could definitely use a pair of feet that can move around in VA, hint, hint!).
I seem to be more up to date now, but unfortunately I have no chance of getting to VA since I live in England 
but I'll help where I can
