Not to open up a festering wound because I don't usually use On Demand, but my kids were home for the holidays and wanted to view it. I have read many of the posts that mention that Comcast offers On Demand for retail TiVos. I got both of mine at Best Buy via the Comcast sales folks there. So I called Comcast. They said tune to channel 1. I did. "Problem with the cable signal on this channel. Trying again." They sent a reset and that did nothing. After 10 mins of hold time, the rep came back on the line and said she checked with someone higher than her: Regardless of whether my Premiere XL has a Comcast M card or not, I am unable to receive Comcast On-Demand programming. She said I need to buy a *Comcast* TiVo and associated M card and THEN I will have access to On Demand. Does this make sense or am I getting jerked around? I am in New England. Thanks.
