If you use the TiVo remote to control power for more than one device, it is possible that one or more devices may not receive the Power On signal (for example, the TV may power on but the A/V receiver may not). Pressing Power again may turn off one device as the other turns on. If this happens frequently, you may need to turn on power for one device individually, either with its own remote or by pressing the Power button on the device itself.
