@nonoise, Thanks for sending me the above TiVo instructions for controlling the volume on my amplifier. My TiVo remote connection issue is solved. I replaced my TiVo remote (broken) with another TiVo remote and followed the TiVo instructions below the ====== exactly as you suggested.
My TiVo remote connected to my Musical Fidelity M6Si amp in about 3 seconds and I can now control the amps volume by the TiVo remote. Thanks again for your help.
==============================
Search for a code to control the volume on your A/V or stereo receiver
1. Cover the end of the TiVo remote control with your hand.
2. Hold down the TiVo and Mute buttons simultaneously until the red (or amber) light on the remote control remains on.
3. Remove your hand from the end of the TiVo remote control.
4. Enter code 1999.
5. After you enter the code, the red (or amber) light will flash three times and then remain on.
6. Press Volume Up once every two seconds. This will test hundreds of codes, one by one. Do not go any faster than this or you may skip over a code that works.
