Here is what I have: HD Antenna --> TIVOHD (Antenna input) Analog Comcast Cable --> TIVOHD (Cable input) TIVOHD --> TV All other TVs in the house work fine with the Analog Cable If I go Cable --> TV without the Tivo I get all the Analog Channels If I go Cable --> TivoHD (no Cable Cards) --> TV During the setup process where it asks to verify a channel is correct I can see the Analog channel in the back ground. I have even told it to try a number of different channels and they all come in on the background as well. BUT! when I finish setup and try to watch live tv I don't get any of the analog channels. I don't even get the analog channel which worked fine during setup. I DO get the OTA HD channels just fine. Should I return the Tivo? Am I doing something wrong?
