Tivo obeys the coding it receives (the CCI byte). If it is set so that you cannot transfer the content, you cannot transfer it anywhere. That can be set at the station/network level, and can be handled differently by local affiliates. I'm not sure if this can be set by the program as well. Commonly, TWC limits everything except network tv, ComCast limits premiums, and other providers have different scenarios.
You can stream anything, as that complies with the rules. Only the premiere can stream.
There are literally a million threads on this, look around and learn more. The comcast specific thread my be good for you to review.
