Advertisements I currently have a series 2 single tuner, with life time service. With my big new HDTV, I'm about to place a call into Comcast to get a HD tuner - however I'm really not sure about spending so much on a series 3 ... I have a couple of questions: Can I transfer my life time subscription (I'm assuming no)? Can the series 2 and 3 communicate and share (non HD) programming? This way I can make use of the Series 2 in another room. I know I'll be losing TivoToGo, so the series 2 would make up for that (viewing in another room). If neither of these are options, I'd probably end up going with Comcast HD DVR and upgrading to the Tivo interface when it swings around.
