This issue has probably been dealt with here but I cant find the thread. Im visiting relatives in MA and trying to help with their Tivo v. Comcast issue. They have 4 S2s, two single tuners and two dual tuners. The two dual tuners will not work with the Comcast equipment. They have Motorola boxes connected in front of all 4 tivos. The dual tuner tivos cant change the channel on the cable boxes. I havent spoken with anyone from Comcast yet but my relatives had a service call and were told the dual tuner tivos dont work with Comcast equipment. Is there any kind of a work around for this issue or has Comcast Massachusetts succeeded in extorting its customers into settling for the Comcast DVR? Thanks in advance.
