Advertisements I recently upgraded to Digital Cable in College Station. We have Suddenlink Digital Cable with the Motorola DCT2524 Cable Box. I tried to hook up my series 2 Tivo. I got through most of the setup but when I tried to hook up the serial cable from the tivo to the cable box I got an error message saying the Tivo was unable to change the channel on the cable box using the serial cable. I have read other forums saying that I should change the manufacturer from Motorola to GI, or call the cable company to make sure the serial port is enabled. Oh and the IR cables are pure junk. Takes about 5 seconds to change the channel and ony works about half the time. Anyone have any suggestions???
