start a VOD video and disconnect the coax cable, if its IP then the video will keep playing, if its coax, if the tivo has a 3-10 second buffer, after that the video will stop
Ok. Now I'm really scratching my head. Back to VOD, I pull the coax and it stops. It needs both connections to run. I am betting the stream itself is over the coax, since that's how their boxes do it. I'm not running any local router meter SW else I'd check that to see if the traffic is there.
