Hello. I just received my HD TIVO. I understood that I'd need cablecards for the "encrypted" digital cable channels, which are coming on friday. However, the TIVO will not pick up the any digital channels without the cablecard. My television has a digital tuner that will pick up all of the unencrypted digital channels just by plugging the coax into the TV. I ran set up and it picked up all the analog and digital channels through the TV without the TIVO. Am I wrong here? Does this TIVO pick up the digital channels that are unencrypted like my television? I may not full understand what encrypted is versus unencrypted is; but remember, my Magnavox Television did pick up all those channels. Thanks so much for your help.
