I want to switch from DirecTV to Comcast but want to stay with Tivo. I understand I need a cable card instead of a Comcast DVR. But, I have two TVs. Does that mean I need two Bolts and two monthly fees? Or Will a Bolt and Mini work? I understand that the Mini needs one of the tuners on the Bold and that it is best to use coax. If I understand correctly, I need an MoC at the Mini for a coax connection. Do I need one at the Bolt? Is this over the Comcast coax or separate? Thanks in advance for any help.
