This has been covered before and I have searched this forum and read all past postings..... ( Selecting TiVo button then Live TV button doesn't reset the function). I upgraded to a new LG C9 OLED TV and now Live Tv button doesn't swap tuners. TiVo and TV are connected to a Onkyo AVR. I can see and swap tuners by selecting info button. Reboot of TiVo re-enables the Live TV button every time. When I turn the TV off then on again this function is lost again until the TiVo is rebooted. Any idea on what signal the LG TV is sending the TiVo?
