Advertisements In TiVo Desktop, it says that if you change the Media Access Key, it will make all transferred recordings on that box not viewable. So how to you handle more than one TiVo box? Is there some type of "master/slave" configuration you need to set on the TiVo Boxes or something like that? Or is the TiVo Box limited to one pairing? What about viewing/transferring recordings between TiVo's?
