This has been working for a long time. But, just the other day, the TIVO remote quit controlling just the TV volume. The TV power on/off and mute still work. The yellow light on the TIVO lights whenever I press the volume up/down button. I tried replacing the remote's batteries, reprogramming the remote, power reset* the tv and TIVO. The TV's remote will change the volume. Any other ideas for me to try? *power reset - I'm a computer tech. So, whenever I have problems with anything electronic I unplug it from electricity for at least 30 seconds, press the power button (if there is one) and then plug it back in.
