Just connected the TIVO - the hardest part so far was untangling and sorting out the myriad wires behind the cabinet emanating from the TV, STB, VHS player, DVD player/recorder, HDD Recorder, Hifi system and CCTV system. I can see life on the TV screen however so all appears to be going well...
Will head off to swap the modem shortly so if you don't hear back from me for some considerable time you'll know it wasn't quite the 10 minute job predicted...
