Actually, you may have to throw in the towel and add one or more ANALOG tuners for your non-digital "favorite" channels since (at least on Mediacom) the CableCard does NOT tune On-Demand channels, you'd need their STB for those. I know the cable providers are working toward a total digital distribution from a cost-effective position -- they can cram more channels into the same bandwidth! I too await the disappearance of analog in its entirety. BTW, Mediacom is offering a "digital to RF converter box" to allow those customers with old analog TVs to watch their all-digital cable.
Isn't it interesting how we can't stand to watch any of the ol' NTSC broadcasts when just 5 years back it was the norm! Sure, HDTV is a fantastic standard with the hi-def video and AC3 audio it's better than the DVDs we watched for so many years and now only BluRay has more to offer.
