I released footage I took from Defcon 12 this past July.

It's Episode 3.
I couldn't depend on my camera this year for Defcon 13. But luckly whitesword got plenty of footage. If I make it next year I'll try to get alot of shit filmed. Hopefully even HD! Then again, I doubt I would release anything online in true HD. That would just take too much bandwidth.
