As far as receiving ondemand via a cablecard in a tivo?? If thats what you asking, no time soon, mcards are not dual path or whatever the term is, there is no current hardware to support ondemand aside the dct
There are 3 markets that I know for sure that you can access Xfinity on-demand though the Tivo. Those are Seattle, Boston, and San Francisco. More are coming but not sure when. How do they like it? I'm thinking of getting one as the DVR in the Seattle market sucks. Only 2 tuners an half terabyte hard drive!
