Musical Fidelity suggested I use the TiVo learning process to make the connection. Unfortunately, I started this process and discovered the TiVo remote used for my test would NO LONGER connect to my main amplifier. This required more time to re-adjust it. I will visit my local cable store and get another backup TiVo remote for further testing.
This is the same issue we had with another amp until my retailer suggested I use the Marantz code 2013 and it connected immediately. Once I get the 2nd remote, I will attempt to connect the TiVo remote to my amp using the methods suggested above. Thanks.
