Advertisements It seems like all the TVs I have requires a two button process to change the input source. One button selects the source (HDMI1, HDMI2,...) and the other one CONFIRMS your choice. I presume they design the remote this way as people complain about inadvertently changing the input. The problem is that if I get the TiVo remote to adopt some functions of the TV remote (power, volume +/-, mute, input) the input button never works since it only does the function of the first button. I bought a TV for my parents and it has another glitch, where if you push the FF button down to hard it changes the input to RF coaxial. I don't know what causes this problem. But since you can't use the TiVo remote to change the input function back to HDMI, you need to get the other remote. My 83 year old father refuses to use the TV for this reason.
