This really didnt peak my interests so I really didnt give it a look until now but I thought I would chime in

The whole capping this thing via firewire is moot for one reason

HDNet and HDNet movies (or whatever its called) is 5C encrypted at all times via the broadcasting network and not the cable distributor

So it doesnt matter if you have Comcast or ATT or FioS or Cox or whatever

I believe its been like that on HDNet for a few years now

Edit: Ill attempt to cap Race for your life CB on Wednesday....but I know it will be encrypted
