Netflix are not mentioned in the copyright information on the TiVo, whereas pretty much everybody that can be mentioned has been. This suggests to me that there is no Netflix component running on the TiVo itself and that they are streaming data over HME. I'm just guessing though. But if it is using HME, I would be surprised if the network traffic to control the streaming was encrypted. I would only expect the video itself to be encrypted. I don't have a Netflix account, so I cannot volunteer with a packet sniffer.
