I recently upgraded my satellite service to the Direct TV HD+ and a HD DVR receiver. Upon receiving my new receiver, I discovered in order to access the On Demand content, the receiver had to be connected to a network, and have internet access. The network setup was simple, connect it to the switch and it grabbed it’s network info from DHCP. This is where the security geek in me got curious: what exactly is this fancy new receiver sending/receiving on the wire?
