Advertisements Just like the S3, it will depend on what your cable company has activated/targeted to your account (cablecards.) It is not up to Tivo, but how the CableCards are programmed to map the channels. It would be the same as what your comcast box would show. It may be possible (but difficult, normal CSR cluelessness) to get them to change the ADS setting for your account, however you prefer. (Sometimes digital is better quality, sometimes analog, depends how good your analog is. ) If you get a digital-only comcast box, that will normally activate ADS for your account. If not, it may default to analog mapping. YMMV.
