I have el cheapo basic cable (around 70 channels) and a cable card to properly get guide data for the HD local network channels. Most of the channels are available on TiVo but some aren't. Guide data is available for these, its just that TiVo won't tune them. All of the TV's in the house can tune all the channels with thier built in tuners. Is this just a mis-configured cable card on TWC's end?
