I’ve been using Netflix’s Instant Queue feature on my TiVo for a few weeks. It works fairly well except for occasional stops to rebuffer, but last week I started getting this message: “An error occurred communicating with Netflix. Please try again.” I called Netflix support and they had me delete the Netflix connection from my TiVo’s “Video on Demand” menu and then connect it again, and now it works. I think what happened is that my TiVo’s IP address changed (which can happen occasionally when the device or the router restarts) and Netflix got confused.
