Advertisements I apologize if this is answered in another thread, I searched but couldn't find an answer. So I had an old Standard def tv with an old series 2 DT Tivo set. We just got a new HDTV and have been subscribers to Comcast Xfinity Digital Cable, including On-Demand. I wanted to upgrade my tivo to the new Premiere, but I heard people say using tivo eliminates the ability to use On Demand. I then saw an ad saying tivo premiere allows you to use the on Demand Service. Excited, I tried to look more into it. All I can find, however, is that Comcast will give you a box with the tivo interface... not really what I was looking forward. I was wondering if someone can clarify this for me once and for all. If I buy a new Tivo Premiere and (I get the necessary Comcast M-card) connect it to my HDTV, will I, in any way, be able to access Xfinity On-Demand? Thanks for your help!
