Have a TiVo HD on software 11.0m-01-2-652 with an Onkyo receiver. I'm using a standard TiVo peanut rewrote. The screens on the TiVo only say that the remote can control AV volume and mute (no mention of receiver power), but can't it control receiver power as well? No matter what code I try, it only controls volume and mute but never the receiver power. What am I missing? Thanks.
