The author of that forum post is unwilling to publish video of the device.
Publishing any sort of video takes a non-trivial amount of time, especially when one has never even attempted to try doing so before. The owner of that device isn't being paid to put that up there. I really don't blame the owner one bit for not wanting to do that, especially when I see attitudes like this. I also don't blame others for NOT wanting to do forums posts like that, when there are attitudes like this.
